| 摘要: |
| 为了激励灵活性资源，电力市场辅助服务市场规则出现了许多变化，例如北美电力市场中辅助服务市场的机会成本、里程价格和运行备用需求曲线机制等。提出了辅助服务定价的一般公式，该公式建立了能量市场与辅助服务市场的关系，阐述了辅助服务市场规则的含义。以抽水蓄能电站为例，基于市场实际运行价格，定量估计了辅助服务市场规则对增加灵活性资源收益的作用。研究表明：所给出的辅助服务定价公式较好地解释了实际市场的价格数据，验证了辅助服务市场定价公式的正确性；里程价格给予灵活性资源更多的刺激，该部分收入约占总收入的10%，而机会成本并没有特别的激励；运行备用需求曲线及其附加电价机制是一种容量补偿机制，且其补偿力度非常突出；目前市场规则下，抽水蓄能电站的主要收益来自能量市场的套利，辅助服务的收益依然处于次要地位。 |

| Abstract: |
| In order to stimulate flexible resources, many changes have taken place in the ancillary service market rules of the electricity market, such as opportunity cost, regulation performance price and operating reserve demand curve mechanism in the North American electricity market. This paper puts forward a general formula of ancillary service pricing, one which establishes the relationship between the energy and ancillary service markets, and expounds the meaning of ancillary service market rules. Taking a pumped storage power station as an example, based on the actual market operating price, we quantitatively estimate the role of ancillary service market rules in increasing the return of flexible resources. The research shows that the ancillary service pricing formula given here better explains the price data of the actual market, and verifies the correctness of the ancillary service market pricing formula. Regulation performance price gives more incentives to flexible resources, and its income accounts for about 10% of the total revenue, while opportunity cost has no special incentives. The operation reserve demand curve and its additional electricity price mechanism is a capacity compensation mechanism, and its compensation strength is very prominent. Under the current market rules, the main income of pumped storage power stations comes from the arbitrage of the energy market, and the income of ancillary services is still in a secondary position. |
