基于智能电网调度控制系统基础平台的新能源优化调度

Renewable Energy Dispatching Based on Smart Grid Dispatching and Control System Platform

针对中国新能源大规模集中式开发的现状,分析了开展新能源调度的必要性以及新能源调度的特点。鉴于目前传统调度技术支持系统功能已无法应对大规模新能源并网给电网调度运行带来的挑战,介绍了一种基于多时间尺度的新能源协调优化调度方法,包括年/月度新能源电量计划制定、日前及日内滚动优化调度,并基于正在推广应用的智能电网调度控制系统基础平台设计开发了新能源调度技术支持系统。通过该系统可实现对新能源进行多个时间尺度的协调优化调度,逐步减少新能源预测误差带来的影响,保证了新能源的最大安全消纳。研究成果已在全国16个网/省级电网实现了应用。

In view of the situation of renewable energy development being large-scale and centralized in China,the necessity and characteristics of renewable energy dispatch are analyzed.Since the traditional dispatching technology supported system has been unable to deal with the challenge posed by large-scale renewable energy integration,a coordinated optimized renewable energy dispatching technology based on multi-time scale is introduced.The dispatching technology includes annual and monthly renewable energy schedule making and day-ahead and intraday rolling optimal dispatching.Based on the basic platform of smart grid dispatching and control system （D5000 platform）,a renewable energy dispatching technology supported system is developed.This system is able to realize coordinated optimized renewable energy dispatching of multi-time scale,while gradually reducing the impact of forecast error and ensuring the security accommodation of renewable energy.The research results are in application in 1 6 regional or provincial grids.
