水电主导的省级多能互补调度系统关键技术及应用

Key Technology and Application of Provincial Multi-energy Complementary Dispatching System Dominated by Hydropower

随着西南地区水电和新能源电站规模的不断增大,开发实用的高比例可再生能源电网发电调度决策系统具有很强的迫切性和现实性。为此,以云南电网为依托,设计开发了多能源电网互补优化调度系统,构建了分层协同的总体技术架构,开发了覆盖新能源预测、径流预测、中长期运行方式优化、短期发电计划编制等全过程发电调度业务功能,集成了多尺度风光水互补优化调度模型与方法。实际应用结果表明,该系统可有效提升水电主导的多能源电网发电调度精细化、自动化、实用化水平。

In Southwest China,aprovincial multi-energy complementary system dominated by hydropower has been formed.The development of generation scheduling decision support system for large-scale wind-solar-hydro hybrid system is urgent.Therefore,based on the actual project of Yunnan power grid,a decision support system for complementary optimal dispatching of multi-energy power grid is designed and developed,and the overall technical framework of hierarchical coordination is constructed.The main functions of the system include wind power and solar power forecasting,runoff forecasting,long-term dispatching,medium-term dispatching and short-term dispatching.The practical application shows that the system can effectively improve the level of refinement,automation and practicality of the management of windsolar-hydro hybrid system dominated by hydropower.
