西北省间实时平衡电力市场探索

新能源出力的波动性和随机性影响电网实时平衡.中国西北电网新能源占比高、平衡资源时空分布不均衡,分省市场实时平衡困难,为此,文中设计西北省间实时平衡电力市场,以发挥西北省间实时平衡能力,适应高比例新能源电网实时平衡需要.首先,结合国内外电力市场建设与西北实时平衡现状,分析了建立西北省间实时平衡市场的必要性;然后,说明了双边竞价的市场运作思路,提出了基于潮流的市场耦合方法的市场竞价出清模型,设计了市场运作流程;最后,讨论了西北省间实时平衡市场与其他市场之间的协调运作,通过模拟算例说明了西北省间实时平衡市场的作用.

Exploration of Cross-provincial Real-time Balancing Electricity Market in Northwest China

The fluctuation and randomness of renewable energy output affect the real-time balance of power grids. Due to the high proportion of renewable energy in the Northwest China power grid and the unbalanced distribution of balancing resources in time and space, it is difficult to achieve real-time balance in provincial markets. Therefore, this paper designs the real-time balancing electricity market in Northwest China, so as to give full play to the real-time balancing ability among provinces in Northwest China meet the needs of real-time balance in power grids with high proportion of renewable energy. Firstly, the necessity of establishing a real-time balancing market among provinces in Northwest China is analyzed based on the construction of electricity markets at home and abroad and the current situation of Northwest China real-time balance electricity market. Then, the market operation idea of bilateral bidding is explained; the market bidding and clearing model based on the flow-based market coupling method is proposed; and the market operation process is designed. Finally, this paper discusses the coordinated operation between the cross-provincial real-time balancing market in Northwest China and other markets, and illustrates the role of the cross-provincial real-time balancing market in Northwest China through simulation examples.
