摘要
在电力市场环境下,运用非线性规划的方法,通过对发电公司在保证期货电量一定原则和考虑处罚情况下利润目标函数的研究,建立了幂级数形式的罚函数模型。并将该函数运用到发电公司的经济调度模型中,形成了对发电公司不按照合约出力情况下的市场约束机制。结合算例,分析并验证了罚函数在期货和现货交易中的约束行为。结果表明,该罚函数模型运用价格杠杆作用对发电公司的市场行为有很强的约束作用,而且形式灵活,能更好地维护电力市场的健康有序交易。
Under a deregulated environment, the profit target function of generation company is discussed based on the principle of assuring electricity futures trading. The model of penalty function in the form of power series is established by using non-linear programming method ,and is applied to economical dispatching model of generation company. Restriction mechanism ,which is produced by the penalty function ,works when the breach of contact. Cased are given to analyze and validate the restriction action of the function respectively in the spot and futures trading markets. The results show that the penalty functon model can effectively maintain the haalthy and ordered trading of electricity market.
