摘　　要：近年来随着中国电力体制的改革,大量售电商参与到电力市场之中。对于部分售电商而言,其可能存在一定的市场影响力,投标行为会对市场出清电价产生影响,进而影响到自身的投标策略。考虑到售电商自身的投标策略对市场出清电价的影响以及出清电价本身的不确定性,文中将市场出清电价分布与价格配额曲线(PQC)相结合,建立了基于PQC的市场出清电价的分布模型,进而建立了售电商在电力市场的投标行为优化模型。同时,研究了不同市场供求关系下对应的出清电价分布情况对售电商投标策略的影响。算例表明,对比不同情况下售电商的最优投标策略,基于PQC的方法可以使售电商更好地适应市场并合理地调整投标策略。In recent years,with the reform of power systems in China,a large number of electricity retailers participate in the electricity market.For some electricity retailers,they may have certain market influence,and their bidding behavior will affect the market clearing price,thus affecting the bidding strategy of themselves.Considering the influence of the bidding strategy of electricity retailers on the market clearing price and the uncertainty of the clearing price itself,this paper combines the distribution of the market clearing price with the price quota curve(PQC),and establishes the distribution model of the market clearing price based on the PQC.Then,an optimization model for the bidding behavior of electricity retailers in electricity markets is established.Meanwhile,in different market supply and demand relationships,the influence of the distribution of clearing prices on the bidding strategies of electricity retailers is studied.The calculation example shows that,by comparing the optimal bidding strategies of electricity retailers under different conditions,the PQC-based method can make the electricity retailers adapt to the market better and adjust the bidding strategies reasonably.
