Dynamic electric vehicles charging load allocation strategy for residential area
A large amount of electric vehicles (EVs) charging load will bring significant
impact to the power system. An appropriate resource allocation strategy is required for securing the power system safety and satisfying EVs charging demand. This paper proposed a power coordination allocation strategy of EVs’ in distribution systems. The strategy divides
the allocation into two stages. The first stage is based on scores assigned to EVs through
an entropy method, whereas the second stage allocates energy according to EV’s state
of charge. The charging power is delivered in order to maximize EV users’ satisfaction
and fairness without violation of grid constraints. Simulation on a typical power-limited
residential distribution network proves the effectiveness of the strategy. The analysis results indicate that compared with traditional methods, EVs, which have higher charging
requirement and shorter available time will get more energy delivered than others. The root-mean-square-error (RMSE) and standard-deviation (SD) results prove the effectiveness of
the methodology for improving the balance of power delivery.
