节能调度中的水火电力最优协调问题

以水电比例高达50%的广西电网为对象,提出了基于现代内点最优化理论的水火电力最优协调模型。把原先由人工完成的电网日调度计划,用模型进行描述和求解。在满足"三公调度"、"节能减排"和水火电力系统运行约束的同时,使指定的购电成本或发电成本目标函数得以优化,达到节能调度的目的。同时,系统对所需的各类调度数据进行统一集成,方便使用,大幅提高了调度计划制度的工作效率。

Optimal coordination between hydraulic and thermal powers in energy-saving dispatch

Based on modem interior point method,a model of optimal coordination between hydraulic and thermal powers is presented for Guangxi power grid,of which the hydraulic power resource is up to 50%.The daily dispatch schedule,which was planned manually before,is now described and solved by the model.While the principle of"Sangong Scheduling"and"Energy Conservation & Emission Reduction"as well as the operating restraints of hydro-thermal power system are satisfied,the objective function of power generation or purchase cost is optimized to realize energy-saving dispatch.Furthermore,different dispatch data needed by system are integrated to ease the application and enhance the working efficiency.
