Real Time Active Power Ancillary Service Using DC Community Grid with Electric Vehicles and Demand Response

The introduction of restructuring the electric power system has led to the scenario, making the customer a significant market/player. This has also made the maintenance of reliability and stability in the power system a financially crucial task. .Self-sustainable community grid is a realization of reliable and stable system at a base level as individual households with solar photovoltaics or other renewable system can sustain itself even if the power grid fails. In this paper, active power imbalance ancillary services provision for the grid using a DC community grid, stabilizing the electric power system is proposed. A community of 100 houses with individual solar installation along with a centralized DC-wind turbine and EV charging station compose the grid that is considered. Different cases of energy imbalance and corresponding system behavior are simulated in MATLAB environment and obtained results indicate that the proposed system ensures a better reliability for the power grid by using the ancillary services.
