摘要
提出了过渡期小火电机组的经济补偿措施,以电网连续可靠供电为约束,以购电成本和发电煤耗最小为目标,建立了双目标节能发电调度模型。为缓解各目标间冲突,增加了各目标权重因子,将模型转化为双目标加权模糊节能发电调度优化模型。算例结果验证了该模型的有效性。
In this paper the economic compensation measures for low-capacity thermal units during transition period is proposed; then taking continuous power supply reliability of power grid for constraint and minimized power purchase cost and coal consumption rate as objective, a bi-objective optimal dispatching model for energy-saving power generation is built. To alleviate the contradiction between the objectives, weight factor for each objective is appended to change the proposed model into optimal bi-objective weighted fuzzy energy-saving generation dispatching model. Results of calculation example verify the effectiveness of the built model.
