摘要
在单一购买方的发电侧电力市场中,大规模电量在中长期合同交易市场中集中竞价,使得市场可能面临巨大的市场风险。从分析中长期合同交易竞争电量比例参数、年度合同(双边交易)电量比例对价格形成机制的影响入手,深入研究了通过合理配置竞争电量比例参数来保证市场价格竞争性形成机制的方法。利用发电公司必须运行率指标,充分考虑竞争者地位、市场供需形势以及机组实际可用情况等因素来评估发电公司对市场价格形成有效竞争性的影响,提出了一种合理配置中长期合同交易模式下的竞争电量比例的计算模型和分析方法。通过算例验证表明,该模型得到的竞争电量分配比例可以保证在中长期合同交易中任何发电公司不具备对任意申报电量任意定价的能力,从而保证市场价格形成的有效竞争性。
In the unilateral electricity market competition among power suppliers, bidding of the large-scale electric quantity in the medium and long-term contract market may cause great market risk. Based on the analysis of the influence of the proportion of competitive electric quantity in medium and long-term contract electricity market and the proportion of year contract （bilateral transaction） to price formation mechanism, a model for calculating the proportion of competitive electric quantity in medium and long-term contract electricity market is put forward to ensure the competitive formation of market price, which uses the index named must run rate of generation companies to evaluate the market power in electricity market with fully considered the factors of eompetitor status, market supply and demand situation as well as the units＇ availability. With a simulation example, it is proved that the proportion of competitive electric quantity calculated by the proposed model can guarantee that there have no generation company has the ability to decide the price of any part of its offered electric quantity in medium and long-term contract transactions, thus guarantees the effective market competition.
