【摘要】：大规模风电跨区输送越来越频繁,加大了受端区域电力系统的调节压力,严重影响了风电的消纳能力。针对这一问题,提出一种基于分段电价的风电消纳方法。该方法以电网公司购电总费用最小为目标,考虑火电和抽蓄各自参与风电消纳的边际成本效益,并通过对风电不同电量部分施行分段电价,使得电网公司、风电厂、火电厂和抽蓄电站等多个主体之间利益均衡,增加系统对风电的消纳,同时从理论上证明该方法与弃风惩罚方法原理上的等效性。仿真算例验证了该方法的有效性。仿真结果表明该方法能够显著减少弃风,在不降低电网企业利益的同时,提高火电和抽蓄电站参与风电消纳的积极性,增加风电企业的收益。
[Abstract]:Large-scale wind power transmission across regions is becoming more and more frequent, which increases the regulation pressure of the power system in the receiving area and seriously affects the absorption capacity of wind power. In order to solve this problem, a wind power absorption method based on piecewise electricity price is proposed. This method aims at minimizing the total cost of power purchase by power grid companies, considers the marginal cost-effectiveness of thermal power and pumping storage participating in wind power consumption, and makes power grid companies and wind power plants through the implementation of piecewise electricity prices on different parts of wind power. The balance of interests between thermal power plant and pumped storage power station increases the absorption of wind power by the system, and the equivalence between this method and the penalty method of abandoning wind is proved theoretically. The effectiveness of the method is verified by a simulation example. The simulation results show that this method can significantly reduce the abandonment of wind, not only not reduce the interests of power grid enterprises, but also improve the enthusiasm of thermal power and pumped storage stations to participate in wind power absorption, and increase the income of wind power enterprises.
