兼容多目标调控需要的新型容量市场机制设计

容量市场是电力市场体系的重要组成部分,能起到补偿固定成本、激励电源投资、保障容量供应等作用,在美国PJM、英国等市场中都有广泛应用.然而以保障供给需要为主的机制设计,导致现有容量市场机制在高比例可再生能源场景应用中存在明显局限性,同时也无法兼顾能源转型发展等多政策目标调控需要.面向未来能源转型可持续发展需要,文章提出了...

Design of Capacity Market Mechanism With Multi-objective Regulation

Capacity market, as an important component of the electricity market, can recover the fixed costs of generators, stimulate the effective investment and ensure the power supply, which has been already widely constructed in PJM(USA), UK and other regions. However, the current design of the capacity market mainly focuses on the power supply guarantee, which is inappropriate for its application under the high proportion of renewable energy circumstances and cannot meet the needs of the multi-objective regulations such as the energy transition and development. In order to achieve the sustainable development and transition of energy, a novel capacity market mechanism coordinated with multi-objective regulations is proposed in this paper. The proposed market, with both satisfying the total requirements of capacity supply and involving the additional energy structure constraints, can effectively promote the energy transition. Meanwhile, the marginal cost of capacity resources can be discovered with comprehensively competitions. Furthermore, this market can adapt itself to the decline in the cost of renewable energy(such as wind or solar energy, etc.) and the changing of market competition situations, which can replace the existing subsidies such as renewable portfolio standard. The simulation of the case study indicates that the proposed capacity market mechanism can meet the requirements of multi-objective regulations including sufficient supply, cost discovery, energy transition and so on. And the problem of energy impossible trinity can be effectively solved.
