高比例清洁能源接入下跨省区交易机制及交易模型研究

随着我国可再生能源装机规模的不断增大，可再生能源出力与负荷地理分布不匹配的问题日益突出，为我国可再生能源消纳带来了更加严峻的挑战。传统的跨省区电力交易机制难以满足我国日益增长的可再生能源消纳需求。文中提出了以跨省区电量交易和富余可再生能源跨省区消纳为主的跨省区交易框架，并建立了支撑可再生能源大规模消纳的跨省区市场交易模型。算例分析结果表明，文中所提跨省区交易市场机制与交易模型能够适应我国可再生能源消纳需求，可支撑电力系统的整体经济性与用能清洁度水平的提高。

Analysis on Inter Provincial Transaction Mechanism and Optimization Model Under Grid Connection of High Proportion of Clean Energy

With the increasing installed capacity of renewable energy in China, the defect of mismatch between renewable energy output and load geographical distribution has become increasingly prominent and it brings more severe challenges to the accommodation of renewable energy. Traditional trans-provincial and interregional power transaction mechanism is hard to meet the increasing demand of renewable energy accommodation in China. For this reason, an inter provincial transaction framework based on inter provincial electric quantity trading and inter provincial accommodation of surplus renewable energy was put forward, and an inter provincial transaction optimization model was established to support the large-scale accommodation of renewable energy. Results of computing example show that the proposed inter provincial transaction market mechanism and the transaction model are adaptable to the demand of renewable energy accommodation in China, and it can support the improvement of the overall economy and energy cleanliness of power system.
