Research on the Impact of Electricity Price Fluctuation on Energy Management Strategy

Abstract

Energy management strategy (EMS) is an effective measure to improve the energy economy, however, where fluctuant electricity and fuel prices were not taken into account. Since price fluctuations have an impact on rule-based energy management strategies, constant price energy management strategies are not optimal. This paper proposes a novel energy management strategy considering price fluctuation of electricity and fuel for plug-in electric vehicles (PHEVs). Firstly, the electricity price data of partial cities during peak and trough periods are counted. Secondly, a SA-PSO algorithm is used in the rule-based energy management strategy to optimize the key thresholds. The influence of electricity price fluctuation on energy management strategy has been analyzed.
