一种计及历史出力规律的风电波动奖惩模型

A Wind Power Fluctuation Rewards and Penalties Model Considering Historical Power Rules

目前,随着风电等可再生能源发电迅猛发展,风电机组直接参与电力市场与其他机组竞争报价,并按批发市场价格结算将成为趋势。同时风力发电的波动性依旧是制约风电发展的主要因素,为此已有不少学者提出了减小风电波动性的有效方法。提出了一种计及风电历史出力规律的风电波动奖惩模型,依据风电在历史周期内的波动性变化规律引入波动性奖惩因子,并带入到风电的电力市场的均衡模型中。通过该模型的算例分析,得到模型提出的奖惩因子对风电商的投标出力产生了一定影响,并且随着风电商的风电波动减小其投标出力会有所提高,从而证明该模型有助于促进风电商自发借助储能等辅助设备以提供波动性更小的风力发电。

At present,with the rapid development of wind power and other renewable energy sources,it will become a trend that wind turbines directly participate in the electricity market to compete with other units for quotation,and the settlement will be at wholesale market price.Meanwhile,the volatility of wind power generation still restricts the development of wind power.For this reason,many scholars have proposed a lot of effective methods to reduce the volatility of wind power.This paper proposed a model of wind power fluctuation rewards and penalties,which considered the history rules of wind power output and introduced the volatility reward and punishment factor according to the volatility of wind power in historical cycle,then brought it into the equilibrium model of wind power market.The example analysis of the model showed that the reward and punishment factors proposed by the model have a certain impact on the bidding power of wind power providers,and with the decrease of wind power fluctuation of wind electricity supplier,its bid output increased,which proves that the model can facilitate wind power providers to adopt auxiliary equipment,such as energy storage,to provide wind power generation with less fluctuation.
