To ensure the flexibility and reliability of the power system demand and supply, demand side management with distributed generation is a tool to manage the high demand. In the present work, the demand side residential energy management for household equipment is investigated. Loads of units are divided according to priority. Every individual load is smart enough to switch on/off itself with respect to the power generated from the distributed source. Experiments are performed using MATLAB Simulink and the results showed improvements in electricity bills. Real-time pricing in the present system of billing is more economical than a flat rate system. When distributed resources are connected with the units, then flat rate billing is also more economical than real-time pricing.

Technological advancements have improved energy efficiency and increased energy requirements requiring improved energy density solutions to optimally utilize the existing landscape. The renewable energy density of urban rooftops can be increased by introducing micro wind farms consisting of vertical axis wind turbines (VAWT). VAWTs do not require directed flow thus a feasible choice. In this paper, the preliminary study for parametric design of horizontal distance between two identical Savonius wind turbines is presented. Three different simulations were performed to reveal important insights about this problem with an inlet velocity of 2 m/s. The results suggest 3D analysis for accurate insights.
