Economic Scheduling Model Considering Different Kinds of New Energy Sources and Efficient Optimization Algorithm Based on QCQP Modeling

摘要: 风电、光伏、储能等新电源形式接入大电网，已成为电网发展的必然趋势。由于上述新型电源与传统水火电运行控制特性上的根本差别，传统经济调度模型与方法已经不能适应多种电源形式下的分析使用需要。为此本文通过深入分析新型电源运行特性，提出了多种电源形式下大电网经济调度模型，并通过引入DisFlow潮流式，将上述问题简化，提出了QCQP快速算法，能够实现对上述问题的高效高精度求解。

Abstract: It is a trend that more and more wind power, photovoltaic and battery storage is integrated into the power grid. Because of the differences between the new energy and traditional one, the original economic model is hard to cover the need of power dispatching. The operation features of the new energy are analyzed in this paper. And an economic scheduling model considering different kinds of energy sources is proposed. By introducing DisFlow power formula, this model can be solved more easily in the way of QCQP algorithm.
