电力市场环境下发电计划关键技术综述

Overview on Key Technologies for Generation Scheduling Under Electric Market Environment

在调度运行发电计划领域,市场化改革打破了长期以来发电厂的计划电量模式,发电计划编制开始面临多方面挑战。为了支撑我国电力市场发展,适应市场化改革带来新挑战,剖析了以英国、美国为代表的国外先进电力市场中发电计划编制模式与方法,提炼形成了市场化下发电计划技术发展的三方面共性特点。通过分析我国市场化改革带来的新变化,探讨未来电力市场发展下发电计划编制将面临的多方面技术挑战。据此提出并阐述了支撑市场化下的发电计划关键技术内容,包括:以源网荷全面互动为基本特征的体系结构、以运行经济性为目标的优化思路。

In the field of generation scheduling for dispatching operation, market-oriented reform has changed the mode of scheduled electric power generation of the power plants for a long time, which brings challenges in generation scheduling compilation in many aspects. In order to support electric market reform in our country and adapt to new challenges, this pa- per analyzes modes and methods for generation scheduling compilation in advanced electric power markets represented by England and America, extracts and forms three aspects of general characteristics of generation scheduling technology under market-oriented reform condition. By analyzing new changes brought by market-oriented reform in our country, it discusses technology challenges in generation scheduling compilation in future electric power market development. Then, it presents and states key technologies for generation scheduling supporting market-oriented reform which includes the system structure characterized as source-network-load interaction and the optimization idea aiming at operation economy.
