摘要
能否完全依靠单一能量市场来确保发电容量充裕性是一个存在广泛争论的重要问题。研究了在完全竞争的单一能量市场中的发电容量充裕性问题,建立了相关的理论分析模型,研究结果表明没有足够的理论依据证明这种市场模式能够确保发电容量充裕性;根据对采用这种市场模式的实际电力市场的运营情况分析,表明了单一能量市场在引导充裕发电投资方面确实存在问题。理想条件下的理论模型分析和现实情况下的影响因素讨论均表明,单一能量市场模式难以确保发电容量的充裕性。这些研究有助于理解和把握电力市场环境下发电容量充裕性问题的基本特征。
It is a widely-discussed important issue to determine whether generation capacity adequacy could be ensured by the energy-only market approach. First, a theoretical investigation is made for this market mode under perfect competition assumption, and it is concluded that there is no enough theoretical evidence that the energy-only market approach could ensure the generation capacity adequacy. Secondly, actual operation performance of those electricity markets employing this market mode is summarized, and it is found that there is some difficulty for this market mode to induce enough generation investment. Both the theoretical results under perfect competition assumption and the operating performance in an actual electricity market environment illustrate that it is difficult for the energy-only market to ensure generation capacity adequacy. The analysis is helpful to the comprehensive understanding of the features of the generation capacity adequacy problem,
