基于连续双向拍卖虚拟电厂竞价策略研究

Continuous Bidirectional Auction-based Bidding Strategy of Virtual Power Plant

为应对化石能源逐渐枯竭、气候环境恶化加剧等问题,全球新能源发电迅猛发展。然而,大规模新能源并网不但给传统的能源市场维持供需平衡带来了极大冲击,也给电力市场带来了一定不可控因素。为充分发挥电价的激励作用,调动供需双方的积极性,提高新能源的消纳水平,提出基于连续双向拍卖的虚拟电厂竞价策略。对基于连续双向拍卖的电力市场交易适用条件、交易方式、成交规则进行分析,建立符合买卖双方交易心理的三阶段报价函数,并进行用户成本计算和误差处理,通过多次仿真测试对比暗标拍卖下的新能源消纳效率以及社会福利,验证了所提基于连续双向拍卖的虚拟电厂竞价策略有利于新能源的充分消纳和电力市场的发展。

In response to the gradual exhaustion of fossil energy and the worsening of the climate environment,global new energy power generation has developed rapidly.However,large-scale grid integration of new energy generation has not only brought a great impact on the conventional energy market to maintain a balance of supply and demand,but also brought certain uncontrollable factors to the electricity market.In order to achieve full potential of the incentive role of electricity prices to mobilize the enthusiasm of both supply and demand,and to improve the level of consumption of new energy,a virtual power plant bidding strategy based on continuous bidirectional auctions is proposed.The applicable conditions,transaction methods,and transaction rules of electricity market transactions based on continuous bidirectional auctions are analyzed to establish a quotation function that conforms to the transaction psychology of buyers and sellers,and to perform user cost calculation and error processing.Through multiple simulation tests,it is compared under the hidden bid auction.The new energy consumption efficiency and social welfare have verified that the proposed continuous bidirectional auction-based bidding strategy for virtual power plants is conducive to the full consumption of new energy and the healthy development of the electricity market.
