Power Quality Improvement and Sustainable operation in A Standalone Micro Grid by Regulating Frequency in A Deregulated Market

Abstract

Cooperative decision-making has always benefited from achieving objectives subjected to system constraints in a microgrid. This paper considers the power balance between generation and load as a significant power quality issue. Hence, frequency regulation is regarded as a primary challenge in the system. When the system operator works towards profit for the power producer, an integrated operation provides a solution. The sources considered in this system are Solar PhotoVoltaics (SPV), FuelCells (FC), Diesel Generators (DG) and Battery driven Electric Vehicles (BEV), where the BEVs operate in Vehicle microgrid mode. A central controller and local controllers are present to operate the generators at desired levels. A cascaded fuzzy controller is designed that chooses the best suitable BEV to be connected to the microgrid. The system is implemented in a MATLAB Simulation environment, and various scenarios and cases have been considered for evaluating the system response and its sustainability.
