摘要
合约市场是电力市场的重要组成部分 ,它通过中长期合约交易降低发电商的市场风险 ,保证电力系统长期安全平稳运营。文中紧密结合我国现状 ,充分考虑各发电公司由于历史原因造成的在市场上竞争能力的差异 ,提出了分组竞价的概念和交易机制 ,在最大限度上保证各发电公司的公正和公平性。提出了分组竞价的合约市场交易模型和算法 ,可以同时考虑上升、下降及混合型报价曲线。算例分析表明 ,这种分组竞价机制能保证交易的经济性和公平性 。
Contract market is an important part of electricity market. It reduces the risks of market participants and guarantees the long-term safety of power system operation. Based upon the practical conditions of Chinese power systems, the concept of group bidding along with corresponding trading mechanism is proposed in this paper which ensures the equality of all power companies to a great extent. The model and algorithm of contract market based on group bidding are presented. Both ascending, descending bidding curves, even complicated one, are considered in this paper. Case study shows that the new model can guarantee the economy and justice of electricity trading and it will provide strong support for power system operation.
