跨区域省间可再生能源增量现货市场设计与实践

我国可再生能源分布与负荷存在不匹配的现象，可再生能源装机容量与市场规模在地域上的逆向分布造成弃水、弃风、弃光等矛盾突出。目前我国已实现全国电网互联，为大范围内消纳可再生能源发电提供了物理条件。为充分利用全网资源，并考虑到可再生能源出力只能在短时间尺度上实现较为准确的预测，文章设计了跨区域省间可再生能源增量现货市场的交易组织体系、交易模型、交易规则和技术支持系统，采用经济杠杆和市场手段来促进受端省份消纳可再生能源的积极性，以提高可再生能源消纳能力。在此基础上，国家电力调度控制中心开展了模拟运行，实践结果表明，跨区域省间可再生能源现货市场在促进可再生能源消纳等方面取得良好的效果。

Design and Practice of Cross-regional Incremental Spot Market for Renewable Energy

The phenomenon that renewable energy distribution does not match load exists in China. The reverse geographical distribution between installed capacity of renewable energy and market size results in problems such as abandoning of water， wind， and solar power. National interconnection of power grid has been achieved in China， providing physical conditions for renewable energy consumption in a wide area. Considering the output of renewable energy can only be accurately predicted in a short time scale， this paper designs a trading model about cross-regional incremental spot market for renewable energy to make full use of network resources. In addition， rules are designed and technical support systems are built， hoping to use the economic leverage and market means to further explore the potential of consumption abilities in energy-importing provinces. On the basis of above model， national power dispatching center has preceded simulation operation. Results show that the spot market has achieved good results in promoting the accommodation of renewable energy.
