Josué Martínez-Martínez is a computer engineering senior student at Ana G. Méndez University at Gurabo, Puerto Rico. The research was titled “Magnetic Field Mapping with a Fluxgate Sensor” for which he won the third-place prize in the Division of Physical and Computer Science. Josué was the project manager in the Honeywell UAV Challenge for Universidad Ana G. Mendez that consisted of creating a UAV from scratch and performing an autonomous mission assigned by Honeywell. Universidad Ana G. Mendez won the first prize in this challenge. Additionally, Josue participated the last summer in the CIESESE summer research program at University of Texas at El Paso. There, he worked on the research titled “Unmanned Autonomous Aerial Navigation in GPS-Denied Environments”. Then, Josue worked on the CIESESE program but at his university during the 2019-2020 academic year in a project titled “A Secured IoT Scheme for Microgrids Monitoring” where he achieved his biggest accomplishment that was publish his first conference paper. Also, during the same year Josué was the Association for Computer Machinery chair where they do some volunteer work. The last summer he received the Mickey Leland Fellowship and he worked remotely in a project in the National Energy and Technology Laboratory of West Virginia developing and applying machine learning algorithms to a pressure gain combustion data.
The use of Internet-connected devices at homes has increased to monitor energy consumption. Furthermore, renewable energy sources have also increased, reducing electricity bills. However, the high cost of the equipment limits the use of these technologies. This paper presents a low-cost secured-distributed Internet of Things (IoT) system to monitor and control devices connected in a polygeneration microgrid, as a combined power system for local loads with renewable sources. The proposed mechanism includes a Wireless Sensor Actuator Networked Control System that links network nodes using the IEEE 802.15.4 standard. The Internet communication enables the monitor and control of devices using a mobile application to increase the efficiency. In addition, security mechanisms are implemented at several levels including the authentication, encryption, and decryption of the transmitted data. Furthermore, a firewall and a network intrusion detection-and-prevention program are implemented to increase the system protection against cyber-attack. The feasibility of the proposed solution was demonstrated using a DC microgrid test bench consisting of a diverse range of renewable energy sources and loads.

A microgrid is a small-scale grid for electricity generation and distribution to small communities using different energy sources such as the sun and the wind. This paper presents a secured IoT scheme to monitor a DC microgrid components for improving its performance. The key idea is to set up a Wireless Sensor Network in which the sensor nodes are connected to a network using the Zigbee protocol and allow external communication through a sink node. A mobile application allows the user to monitor and control the system via the Internet to minimize the waste of energy. For security purposes, data are authenticated, encrypted, and decrypted for avoiding malicious attacks. In addition, the sink node has an encrypted key-based protocol for establishing a secured remote login with the authorized users. Also, a firewall and network intrusion detection & prevention system was implemented to protect the devices and their local data. Our results demonstrate the feasibility of this proposed scheme in a real microgrid.
