我们分析了远期容量市场（FCM）的有效性与长期合同在电力市场中的可再生能源的份额不断增长的存在。一个基于代理的模型用于此分析。当可变可再生能源的份额增加时，发电能力市场可以弥补投资可控发电厂的积极性下降，但本身可能造成价格波动。例如，在联合王国，已经发展了具有长期合同的容量市场，以稳定容量价格。在我们的分析中，一个FCM是有效的，在提供所需的充足性水平，并导致更低的成本，消费者和更稳定的容量价格，相比，每年的容量市场。在需求冲击的情况下，FCM可能会形成一个投资周期，但它仍然保持供应安全。其对电厂组合的主要影响是更多地投资于调峰电厂。
We analyze the effectiveness of a forward capacity market (FCM) with long-term contracts in an electricity market in the presence of a growing share of renewable energy. An agent-based model is used for this analysis. Capacity markets can compensate for the deteriorating incentive to invest in controllable power plants when the share of variable renewable energy sources grows, but may create volatile prices themselves. Capacity markets with long-term contracts have been developed, e.g. in the UK, to stabilize capacity prices. In our analysis, a FCM is effective in providing the required adequacy level and leads to lower cost to consumers and more stable capacity prices, as compared to a yearly capacity market. In case of a demand shock, a FCM may develop an investment cycle, but it still maintains security of supply. Its main effect on the power plant portfolio is more investment in peak plant.
