摘要

随着电力市场化改革的推进和可再生能源占比的提高，如何评估并保障系统发电容量充裕性成为确保电力可靠供应的重要问题。文中提出一种可以定量计算每台发电机组充裕容量和系统发电容量充裕度的方法，从而评估机组可靠性价值和系统发电容量充裕性水平。基于发电容量充裕性评估方法和边际成本定价原理，设计一种发电容量充裕性保障机制。容量电价根据年度峰值负荷期间运行的边际机组的投资成本确定，充分考虑机组实际发电能力及系统实际需求来核定补偿容量，从而帮助发电企业在计划投资回收期内回收固定成本，保障系统发电容量充裕性。算例仿真验证了所设计的机制的有效性和适应性。

Abstract

With the advancement of electricity market reform and the proportion increase of renewable energy

how to evaluate and ensure the adequacy of system power generation capacity has become an important issue to ensure reliable power supply. This paper proposes an evaluation method to quantitatively calculate the sufficient capacity of each generation unit and the power generation capacity adequacy of the system

so as to reflect the reliability value of generation unit and the level of power generation capacity adequacy of the system. Based on the evaluation method of power generation capacity adequacy and the principle of marginal cost pricing

a guarantee mechanism for power generation capacity adequacy is designed. The capacity price is determined according to the investment of the marginal unit operating during the peak load period of the year

and the compensation capacity is determined by fully considering the actual power generation capacity of the units and the actual demand of the system. All these measures help power generation enterprises recover fixed costs within the planned payback period and ensure the power generation capacity adequacy of the system. Example simulations verify the effectiveness and adaptability of the designed mechanism.
