Today, the power system operation represents a challenge given the security and reliability requirements. Mathematical models are used to represent and solve operational and planning issues related with electric systems. Specifically, the AC optimal power flow (ACOPF) and the DC optimal power flow (DCOPF) are tools used for operational and planning purposes. The DCOPF versions correspond to lineal versions of the ACOPF. This is due to the fact that the power flow solution is often hard to obtain with the ACOPF considering all constraints. However, the simplifications use only active power without considering reactive power, voltage values and losses on transmission lines, which are crucial factors for power system operation, potentially leading to inaccurate results. This paper develops a detailed formulation for both DCOPF and ACOPF with multiple generation sources to provide a 24-h dispatching in order to compare the differences between the solutions with different scenarios under high penetration of wind power. The results indicate the DCOPF inaccuracies with respect to the complete solution provided by the ACOPF.

The potential for generating electricity with photovoltaic systems is high in Colombia given its geographical position in the tropic. Some departments in Colombia have low electricity coverage and high rates. In the department of Putumayo there is a low coverage rate and high energy costs, while the solar radiation potential is high. Due to the geographical differences of the Putumayo subregions, the radiation potential for electricity generation is unknown. In addition, in this department the energy tariffs are above the national average. The objective of this paper is to determine the effective potential for solar photovoltaic power generation in the Putumayo department with a detailed methodology considering the information of different remote database and meteorological stations and some technical conditions. It was found that the highest effective solar potential occurs in the Amazon region, and the lowest in the Andean region in the Putumayo. On the other hand, when evaluating electricity consumption and tariffs in the regions, it is concluded that consumption can be satisfied with photovoltaic systems by producing self-generating electricity and distributed generation.

The integration of Information Technology (IT) systems (computations and communication—the cyber world) with sensor and actuation data (the physical world), can introduce new, and fundamentally different approaches to security research in the growing field of Cyber-Physical Systems (CPS), when compared to other purely-cyber systems [1]. Earlier work [2, 3, 4, 5] have shown that because of the automation and real-time requirements of many control actions, traditional security mechanism are not enough for protecting CPS, and we require resilient control and estimation algorithms for true CPS defense-in-depth [6]. In this chapter we outline how attacks and resilient mechanisms can affect and defend power grid operations.

The identification of critical transmission lines and critical substations in power systems is prerequisite for security assessment studies because it provides effective schemes to analyze critical contingencies. Sometimes the power network exhibit high vulnerability related with critical transmission lines interconnecting critical substations from a physical point of view. This chapter describes a method to quantify the relative importance level of each substation for the connectivity of the whole network. Vulnerability studies are performed effectively using information about critical tie lines and about critical substations. Additionally, this chapter presents some security studies based on the critical tie lines connecting subnetwork using the so-called Power Transfer Distribution Factors (PTDFs).

The structure of the power system networks is a function of the status of each transmission line. Our focus in this chapter is on the topological assessment with the objective to develop a practical scheme to identify the tie lines that connect the constituent sub-networks in the grid structure. We develop a useful topological characterization of the power system network based on graph theoretic concepts to gain insights into its structural properties. The identification of multiple sub-networks provides effective schemes to analyze critical contingencies.

Objetivo: Al considerar la vulnerabilidad del sector eléctrico colombiano al cambio climático y los posibles riesgos que pueden presentarse como: incumplimientos en obligaciones de energía firme (OEF) por las unidades de generación, los atrasos de proyectos de generación con energía firme comprometida (caso Hidroituango entre otros) y la disponibilidad de energía firme en el mercado, implican un riesgo sistémico para la provisión de energía eléctrica a mediano plazo. Por tanto, este artículo realiza un análisis de riesgo con base en las previsiones y consideraciones aplicadas en documentos técnicos oficiales y resoluciones vigentes de la Comisión de Regulación de Energía y Gas (CREG) en el balance de demanda y OEF a mediano plazo, con el fin de determinar el riesgo existente y las acciones que la entidad debe realizar para mitigarlo. Metodología: A través del estudio sistemático de documentos técnicos y resoluciones recientes de la CREG, se llevó a cabo una reconstrucción de los balances de obligaciones de energía firme (OEF) y demanda proyectada a mediano plazo (cinco vigencias desde 2018 – 2019 hasta la 2022 – 2023) con información proveniente de operador del sistema eléctrico (XM), con el fin de llevar a cabo análisis basados en dos (2) escenarios considerados en documentos técnicos de la CREG relacionados al tema (Doc. CREG 050-2018 y Doc. CREG 075-2018), determinando así las fuentes de riesgo y las medidas adoptadas al respecto. Resultados: Acorde con los escenarios planteados y al análisis de riesgo realizado en este artículo, se observó que la cantidad de OEF actual, en especial para el segundo escenario planteado, requiere toda la energía firme para el cargo por confiabilidad (ENFICC) base que pueda ofrecer Hidroituango, a pesar de ser un proyecto con atrasos y que probablemente no pueda ingresar para las vigencias donde hay riesgo de desabastecimiento, por lo cual es pertinente solicitar una subasta de reconfiguración para esas vigencias. Conclusiones: Se confirma la alta probabilidad de riesgo de desabastecimiento para la última vigencia bajo estudio (2022-2023) en los dos (2) escenarios propuestos por la CREG, dado el nivel de ENFICC incrementales (ENFICC con riesgo de oportunidad) y por la disponibilidad de energía firme disponible para satisfacer la demanda, en especial por las OEF adquiridas por el proyecto Hidroituango. (déficit de 2500 GWh-año y 4550 GWh-año respectivamente). Financiamiento: Universidad Autónoma de Occidente.

The high integration of wind energy in power systems requires operating reserves to ensure the reliability and security in the operation. The intermittency and volatility in wind power sets a challenge for day-ahead dispatching in order to schedule generation resources. Therefore, the quantification of operating reserves is addressed in this paper using extreme values through Monte-Carlo simulations. The uncertainty in wind power forecasting is captured by a generalized extreme value distribution to generate scenarios. The day-ahead dispatching model is formulated as a mixed-integer linear quadratic problem including ramping constraints. This approach is tested in the IEEE-118 bus test system including integration of wind power in the system. The results represent the range of values for operating reserves in day-ahead dispatching.

En Colombia el área de las zonas no interconectadas a la red eléctrica corresponde al 50%, en particular, en el departamento del Putumayo hay un bajo índice de cobertura. Por otro lado, el potencial en energía solar es considerado alto, sin embargo, en regiones como el Putumayo, debido a las diferencias geográficas de sus subregiones, se desconoce con exactitud su valor. En esta investigación se determinó el potencial efectivo para la generación eléctrica solar en el Putumayo considerando restricciones técnicas y geográficas a partir de la información de múltiples bases de datos. Se encontró que el potencial efectivo solar más alto se da en la región Amazónica, y el más bajo en la región Andina. Por otro lado, al evaluar el consumo de energía eléctrica de las regiones, se concluye que se puede satisfacer esta necesidad con sistemas fotovoltaicos al producir energía eléctrica de autogeneración y generación distribuida

In the day-ahead dispatching of network-constrained electricity markets, renewable energy and distributed resources are dispatched together with conventional generation. The uncertainty and volatility associated to renewable resources represents a new paradigm to be faced for power system operation. Moreover, in various electricity markets there are mechanisms to allow the demand participation through demand response (DR) strategies. Under operational and economic restrictions, the operator each day, or even in intra-day markets, dispatchs an optimal power flow to find a feasible state of operation. The operation decisions in power markets use an optimal power flow considering unit commitment to dispatch economically generation and DR resources under security restrictions. This paper constructs a model to include demand response in the optimal power flow under wind power uncertainty. The model is formulated as a mixed-integer linear quadratic problem and evaluated through Monte-Carlo simulations. A large number of scenarios around a trajectory bid captures the uncertainty in wind power forecasting. The proposed integrated OPF model is tested on the standard IEEE 39-bus system.

The characterization and proper simulation of PV systems is a requirement to carry on feasibility studies of distributed generation. The detailed simulation of PV arrays guarantees an efficient operation considering different conditions. This paper addresses the characterization of basic PV cells and also includes the construction of PV modules with enough details to obtain relevant information about the performance. This paper shows how the I-V curves are affected by the temperature and other parameters. The models used and characterized correspond to commercial panels of first generation modules used widely in projects.

This paper focuses on the characterization of markets using a network to capture some properties such as the formation of congestion zones given by the coherence of locational marginal prices. We overcome the data handling and heavy computing demands of locational marginal prices (LMP) by characterizing the market layer in a network weighted by the LMPs differences, which are due to system congestion and so are merely manifestations of binding constraints in the transmission network. We exploit extensively the salient topological characteristics of large-scale interconnections. Understanding the complexity of a market layer may be useful to economists, regulators and also to market participants.

The rapid increase in the integration of distributed resources such as distributed generation (DG), demand response (DR) and electricity storage (ES) requires management schemes to integrate distributed resources into low and medium electricity networks. Energy management represents a challenge for operation of electric grids when distributed resources are merged into the network. This paper address the energy management of distributes resources considering a complete characterization of them. The feasibility of those resources is considered into a microgrid model, so, the distributed resources are integrated through of a microgrid. This paper proposes the integration of distributed resources using a microgrid concept because there are relevant advantages of this model. The operational advantages are evident from the results. The results show how effectively different energy resources can be managed into the grid in the most efficient way.

The new resources available in power system require a new agent to manage these resources in the most efficient way. Resources provided by the supply side or the demand side can be managed together in order to provide some services to the grid. New resources such as massive electric vehicle and distributed generation have been being gradually integrated to the grid and for the next years the integration tendency will follow increasing. These resources require a different approach to be managed adequately. The integration of intermittent resources into the grid is a challenging area but these issues can be addressed by an aggregator agent. On the other hand, the demand of power required by electric vehicle integration can impact the load curve of different distribution system far from its capability. An aggregator agent also can be useful to manage adequately the demand required by Electric Vehicles. This paper proposes an energy aggregator model (EAM) to manage power transactions between the grid and the demand side resources.

We develop a graph theoretic approach to study topological properties of power smart networks based on the information available into the Network Topology Processor (NTP) which is a module of the Energy Management System (EMS). The NTP module continuously retains and updates electrical system topological information such as node-branch network connectivity, open-ended lines and transformers. We use this information to study two structural properties: the robustness and the connectivity. We explicitly quantify the robustness of the system and identify strongly connected subnetworks. The topological information deduced in this paper is useful for network security assessment of the system. The capabilities of the proposed approach are illustrated on one large scale network. Others topological properties could be studied based on this formulation.

Secure operating conditions must be maintained under different events. This paper proposes the creation of islands as a strategy that consists of tripping off properly selected lines in order to separate the power network into islands as a way to improve the security of the power system. In the last decade, several collapses have occurred around the world. This defensive strategy would allow safeguarding the power system when cascading failures spread rapidly through of the interconnected network. The strategy proposed in this paper is based on Spectral Graph Theory. Graph eigenvalue analysis provides some insight into the intrinsic structure of the power systems. The concepts are illustrated by splitting of the 68-bus test systems into islands. Finally, the paper offers a dynamic analysis of the 68-bus test system to demonstrate how the splitting strategy would work.
