摘要
针对售电商从发电商那里以不确定的批发价格购电,然后以相对稳定的电价出售给电力消费者,通过构建模型来描述发电商-售电商之间的Stackelberg关系,研究竞价上网和管制零售电的混合型电力市场中间歇性可再生能源发电的投资决策。进而,借助随机仿真法拟合可再生能源电波动在时间上的自相关性和实时电价的均值回归性,重点研究间歇性可再生能源的可得性与最优产能组合,仿真模拟发电投资的最优容量决策;探讨实时价格波动性和供给不确定性对实时电价的影响,为可再生能源发电实践提高决策的效率。
In hybrid electricity markets which consist of a competitive upstream wholesale market and a regulated downstream markets,an electricity retailer purchases electricity from generator in the whole-sale electricity market with a volatile spot price and then sells it to end consumers at a fixed regulated price.In this article,we model the Stackelberg game between the electricity retailer and generator and then examine their investment decisions.By capturing the auto-correlated characteristics of wind speeds and mean reverting characteristics of spot price through stochastic stimulation,we find the optimal mix of renewable energy source electricity(RES-E)and convention electricity,explore the impact of spot price fluctuation and supply uncertainty on spot price and thus improve the efficiency for RES-E promotion.
