考虑电动汽车有序充电的电网低谷调峰优化研究

Research on Optimization of Peak Regulation in Valley Time of Power Grid Considering Orderly Charging of Electric Vehicles

针对上海地区受电比例逐年增大所带来的低谷调峰困难问题,提出了一种分时电价下电动汽车有序充电参与低谷调峰的策略。在上海电网原有峰谷电价的基础上,制定了合理的分时电价体系。以系统运行成本最低为目标,建立了含电动汽车有序充电的低谷调峰优化模型。根据上海电网实际算例,采用优化软件Lingo进行求解,验证了该策略的有效性和可行性。

Aiming at the difficulty of peak regulation in valley time in Shanghai brought about by the power receiving proportion which increases year by year,a strategy of peak regulation in valley time is proposed based on orderly charging of electric vehicles at the time-of-use price.On the basis of Shanghai power grid’s original peak valley electricity price,a reasonable time-of-use price system is formulated.An optimization model of peak regulation in valley time is established which contains orderly charging of electric vehicles aiming at the lowest operating cost of the system.According to the actual example in Shanghai power grid,the commercial optimization software Lingo is used to solve the model,verifying the effectiveness and feasibility of the strategy.
