计及网损的快速经济调度方法
摘要:若网损近似为常数,对机组费用曲线满足凸特性的经济调度可解析求解,而网损实际是随机组功率变动而变动的,使这一解析求解的方法不能直接使用。对此,借助网损与机组功率间存在的线性凸特性的规律,依据潮流方程,提出网损随机组功率变动的快速经济调度算法,该算法将网损变动的经济调度问题转化成网损不变经济调度可解析的序列组合,使其在单调有限次代数计算后获得经济调度最优解。
Abstract:When power network losses are assumed to be constant, an analytical solution was proposed to solve the economic dispatch problem given the unit consumption characteristics are convex. However, as the losses are actually varying with the outputs of the power generating units, the previous analytical method cannot be applied directly. Fortunately, based on the convexity of losses related to the unit's power output as well as power flow equations, this paper proposes a fast-analytical method for economic dispatch with consideration of network losses. The proposed method converts the problem into several economic dispatch problems with constant losses and the optimal solution can be found in monotone finite algebraic calculus.
