摘要
为解决仅实施分时电价政策时电动汽车响应会引起新的负荷峰谷差问题,基于动态非合作博弈的主从博弈思想,提出了基于电价和碳配额双重激励协同博弈的含电动汽车微电网的优化调度策略。该模型考虑新能源发电完全消纳,针对等效负荷曲线制定分时电价和碳配额双重激励政策,以微电网侧为主体,以运行成本最小和极小化负荷均方差为主体侧优化目标;以电动汽车车主侧为从体,以电动汽车成本最低为目标;采用粒子群算法并利用模型解耦特性由内至外求解优化模型纳什均衡点,获得微电网侧最优分时电价和电动汽车充放电方案的集合。通过算例详细对比分析了优化前后各种典型场景,验证了所提模型的削峰填谷效果和整体调度效益。本文的多重政策协同激励策略思想可为电力系统需求侧响应的相关工程实践提供借鉴。
In order to solve the problem of new peak-valley load difference caused by the electric vehicle response when only the time-of-use price is implemented,based on the master-slave game theory of dynamic non-cooperative game,an optimal scheduling strategy for micro-grids containing electric vehicles is proposed based on the double incentive and cooperative game of electricity price and carbon quota.The model considers the complete consumption of new energy generation,and it formulates dual incentive policies for time-of-use prices and carbon quotas through equivalent load curves,with the micro-grid as the main body,and the minimum operating cost and mean square deviation of load as the main optimization goals.The owner side of the vehicle is the slave and the lowest cost of the vehicle is the related goal.The particle swarm optimization is adopted and the decoupling characteristic of the model is used to solve the Nash equilibrium point of it so as to get the collection of the optimal time-of-use price and the charging and discharging scheme of the electric vehicle.Through a comparative example,various typical scenarios before and after optimization are analyzed in detail,and the effects of peak-cutting and valley-filling and overall scheduling benefit of the proposed model are verified.The multiple policies collaborative incentive strategy in this paper can provide a reference for the relevant engineering practice of power system demand side response.
