摘要:
基于工程项目的经济分析提出的天然气分布式冷热电联供能源系统DES/CCHP昼开夜停协同电网调峰、实现互利双赢的集成创新，展望了可再生能源为主的互联网＋智慧能源时代能源系统的新架构和电力供需时变性的新挑战，论证了作为能源互联网基础单元的16 h/d运行的DES/CCHP和带储电的光伏为主的DES将成分别成为电网昼夜调峰和随机调峰的主力，并指出电力交易的市场化改革、与DES同步的微电网建设和配电网改造，以及建立在互联网、大数据、云计算和人工智能的基础上SG和IEN系统的建设是实现电力供需平衡的决定因素。 Abstract:Based on the integrated creation at synergy of DES/CCHP with grid peak-shaving, which results win-win, the new energy hierachy and new challenge in grid power-balancing at the era of renewable energy and Internet + Intelliget Energy are foresighted. It is predicted that large-scale DES/CCHP operating as 16h/d and photovoltaic-based small-scale DES with power-storage will be the main approaches for the day/night and stochastic grid power-balancing respectively. Finally, it is pointed out that reform towards marketing mechanism for electricity trading, intelligent micro-grid constructing and distribution network reforming, as well as the march towards Smart Grid and Energy Internet by mean of Internet, Big-data, Cloud Computing and Artificial Intelligent, are the determinated factors.
