The demand response support under weather impacts using PV generation and EV energy storage

Abstract

This paper investigates the impact of the grid integration of roof-top Photovoltaic (PV) generation and Electric Vehicles (EVs) energy storage on the demand response. The risk indices are introduced and risk map is created to predict the potential weather impact on the PV and EV owners. Based on the predictions, the aggregator bidding strategies to enable the EVs' stored energy and PV generation to participate in the ancillary service market considering the stochastic behavior are proposed. The role of programs for demand-side management (DSM) (in daily operation) and outage management (OM) (when fault happens) to mitigate the negative weather impacts on the customers is explored. Numerical experiments are implemented to validate the proposed approach and illustrate the impact of PV generation and EVs' ability to charge/discharge the stored energy on the flexibility of the electricity customer demand.
