Power management of harmonic polluted active distribution network in the presence of integrated unit of electric spring and electric vehicles parking lot

This paper presents the optimal scheduling of active distribution network (ADN) with linear and non-linear loads in presence an integrated unit electric spring vehicle parking lot (IUEE). The proposed scheme is formulated form three-objective optimization, which minimizes expected operating cost ADN, voltage deviation function (VDF), total harmonic distortion (THD) separate objective functions. Constraints include power flow (HPA) equations, operation quality limits, model IUEE. has uncertainties load, energy price, demand EVs, are modelled here using stochastic programming. Next, sum weighted functions method as a subset Pareto optimization technique adopted to extract single-objective problem. Then, Sine-Cosine Combined Algorithm (SCA) Gray Wolf Optimization (GWO) used achieve solution. In end, by examining numerical results obtained from implementation on 69-bus capability design enhancing economic situation, operation, ADN compared studies IUEE confirmed.
