市场环境下容量补偿机制对投资的影响分析

Impact of capacity compensating methods on generation investment

针对市场环境下的发电机组投资问题,构建了一个市场环境下发电机组静态投资的智能代理仿真模型,基于该模型讨论了英国容量费补偿模式和两部制定价方法对发电机组投资的影响。结果表明,英国容量费方法对发电容量投资的刺激作用非常有限,而两部制电价方法对投资的激励作用平稳而有效,但是明显存在过投资的危险。发电容量补偿方法对于发电容量投资的刺激作用不仅仅取决于补偿量的大小,同时也取决于补偿的对象与途径,有关容量补偿问题还需要进一步研究。

In this paper, an agent-based simulation model of static investment in the market circumstance is developed according to the problem of generation investment in the market. It discusses the impact of the British capacity compensation model and the two-step pricing method on generation investment. The results show that the British capacity compensation method has limited influence on generation capacity, and the inspiration of the two-step pricing method on investment is smooth and effective, but it will cause over-investment. The influences of capacity compensating methods on the investment will not only depend on capacity compensation, but also depend on how to be compensated and how to compensate, so how to choose suitable capacity compensation needs further study.
