电力市场条件下无功支持服务补偿成本分析ANALYSIS ON COMPENSATION COST OF REACTIVE POWER SUPPORTING SERVICE UNDER POWER MARKET
温步瀛,陈冲,程浩忠
摘要(Abstract)：
在电力市场条件下发电厂为系统提供无功功率支持是一种重要的辅助服务,也是保证系统安全稳定运行、提高电能质量、降低损耗、确保电能交易顺利进行的有效手段,所以必需对无功支持服务进行综合的成本分析。作者从发电厂和电网两方面综合分析了发电厂无功支持服务的补偿成本,根据发电机的运行极限分析了机会成本的产生机理,并获得从发电侧提供无功支持服务的直接成本分布函数。又从电网侧分析无功支持服务对系统的贡献情况,探讨其系统贡献成本。在市场条件下发电厂提供无功支持服务应得到来自两方面的综合经济补偿,以便引导无功容量投资和保证电力系统安全稳定运行。
