摘　　要：介绍了实用当量电价法的基本原理和有关操作事项 ,包括其右端点原理。它不仅很好地解决了电力市场的两难问题 ,而且具有 1 0个优良市场特性 :既保证了市场效率 ,又给予充分合理的投资回报 ,满足了第 1市场原则 ;提供了正确的短期经济学信号 ;提供了正确的长期经济学信号 ;无须设置价格上限 ,自动抑制价格尖峰 ;通过设置容量成本参考系 ,实现有效合理的政府监管 ;自动抑制发电厂商的不良报价行为 ,实现价格策略的稳健性 ;自动抑制发电厂商的持留容量行为 ,实现产量策略的稳健性 ;电价成分可分 ,便于对“新厂”和“老厂”实行不同的财税及金融调控 ,实现第 2市场原则 ;易于理解 ,易于实现 ,易于监管 ;引入新要素后的可扩展性 ,目前 ,已扩展了从发电、输电到辅助服务等近 1 0个核心模型及算法 ,几乎是一个区域电力交易市场所必需 ,初步形成了当量电价理论体系。此项成果的启示和意义在于 :在电力市场结构还很不完美的寡头竞争条件下 ,比之高成本的资产拆分和系统扩容 ,一个低成本的当量电价体系辅以合理的政府监管 ,同样可以实现相当完美的市场特性 ,在政府与市场、交易与投资、效率与公平。Practical electricity value equivalent (p-EVE) pricing method for pool purchase is introduced. Then a right terminal principle of p-EVE is represented. Furthermore ten market characters of p-EVE pricing method for pool purchase are described. They are: Not only possess market efficiency, but also return investment adequately and reasonably; Provide correct short-term economics signal; Provide correct long-term economics signal; No need to set price cap, and the price peak can be restrained automatically; Easy to realize government regulation using a capacity cost reference framework; Restrain the price stratagem of suppliers, robustness in bidding; Restrain the product stratagem of suppliers, robustness in capacity withholding; The price components can be separated for finance operation;Easy to understand and operate; Ten EVE pricing methods for different transactions in electricity market have been expanded and an EVE pricing systems has been developed. The contribution of this research is that a 'nearly perfect' electricity market could be constructed by an EVE pricing systems with lower cost under the reasonable government regulation even if for an unperfected oligopoly competition and/or capacity inadequate electricity market. This key project is supported by National Natural Science Foundation of China (No. 59937150).
