建立了一个能考虑输电网络约束的区域双边电力市场线性供应函数均衡(LSFE)模型，并分析了在传输线路发生不同阻塞情形时，有套利和无套利不同的假设对发电商市场力、市场平均电价和网络所有者的不同影响。采用基于非线性互补方法的改进的 Levenberg-Marquardt 算法来求解均衡解。30节点的 IEEE 测试系统计算结果表明，套利者的出现可以起到降低市场电价、限制发电商市场力的作用，同时有利于整个市场社会福利和消费者利益的提升。
A linear supply function equilibrium (LSFE) model of regional bilateral power market considering the constraints of transmission networks is established. The assumptions of different arbitrage and no arbitrage in different blocking scenarios of transmission line are analyzed. The market power and market average Different effects of tariffs and network owners. The improved Levenberg-Marquardt algorithm based on nonlinear complementary method is used to solve the equilibrium solution. The calculation of 30-node IEEE test system shows that the emergence of arbitrageurs can reduce the electricity price in the market, limit the market power of power suppliers, and at the same time promote the social welfare and the interests of consumers in the whole market.
