面向园区微网的“源–网–荷–储”一体化运营模式

“Source-Network-Load-Storage” Integrated Operation Model for Microgrid in Park

园区微网是多能互补、能源互联网等能源新业态的重要落地点。但是目前我国微网运营缺乏成熟的运营模式和合理的投资回报途径。立足于我国新一轮电力体制改革和能源互联网的背景,分析微网的概念特征以及在能源系统演化发展趋势中地位,提出微网运营主体一体化和投资主体多元化的模式框架,从＂源–网–荷–储＂优化控制运行、微平衡市场交易、内外两级购售电、网对网辅助服务、内外两级需求侧响应、新型备用容量机制建立面向园区微网的＂源–网–荷–储＂一体化运营模式,提出传统运营模式和一体化运营模式下微网经济性分析方法,通过算例分析验证一体化运营模式能够增加微网收益来源,保障微网合理的投资回报,将极大促进园区微网的健康和可持续发展。

Microgrid in park is an important landing place for multi-energy complementation,Energy Internet and other new energy formats.However,there are no mature operation models and reasonable return approaches on the investment for microgrid in China now.Base on the background of new power system reform and Energy Internet,this paper firstly analyzes concept and characteristics of microgrid and its location in the evolution of energy system.Then,model framework of diversified investment and integrated operation is put forward.Next,＂source-network-load-storage＂ integrated operation model in micro-gird is put forward,which includes ＂source-network-load-storage＂ optimization control,micro balance market trading,internal and external electricity purchase and sale,network to network auxiliary service,internal and external demand response and new reserve capacity.Finally,economy analysis method of microgrid based on traditional operation model and integrated operation model is put forward and verified by example.Integrated operation model will increase source of microgrid income,guarantee reasonable return on microgrid and greatly promote the health and sustainable development of microgrid in park.
