摘要
新能源装机容量的逐年提升导致系统面临巨大的新能源消纳压力,跨区域省间电力现货市场作为区域电网中重要的电力余缺互济手段,仍面临市场运行效率较低以及省间壁垒严重的问题。如何进一步挖掘各省份的备用互济能力,缓解能源富余省份新能源弃电和部分省份电力紧缺问题,已成为下一阶段省间电力现货市场建设的关键抓手。以省间市场社会福利最大为目标,构建综合考虑各省备用缺额容量、备用空间互济以及省间输电费用与网损的省间电力现货出清模型。通过考虑备用互济的省间电力现货出清实现了省间电力资源的优化配置,有效降低省内新能源弃电电力,缓解区域内电力资源逆向分布。以IEEE39节点系统和某网调电网构建省间电力交易出清算例,验证了所提模型的合理性和实用性。
The installed capacity of new energy increases year by year,resulting in huge new energy accommodation pressure on the power system.The regional inter-provincial electricity spot market,as an important means for power sharing in regional power grid,still faces such problems as poor market operation efficiency and serious inter-provincial barriers.It is a key tool for constructing the inter-provincial electricity spot market to further tap the reserve sharing capacity of each province and alleviate the new energy curtailment problems in energy-rich provinces and the power shortage problems in energy-poor provinces.An inter-provincial electricity spot clearing model is constructed with the maximum social welfare of the inter-provincial market as the objective,which comprehensively considers the reserve shortage capacity,reserve capacity sharing,inter-provincial transmission cost and network loss.The optimal allocation of inter-provincial power resources is realized by the inter-provincial power spot clearing with consideration of reserve sharing,which effectively reduces the new energy curtailment within a province and alleviates the reverse distribution of power resources in a region.A case study of an IEEE 39-node system and a regional power grid for inter-provincial power transaction clearing has verified the rationality and practicability of the proposed model.
