Benefit Analysis Model And Its Application Of Economic Dispatch For Power Grid

Grid optimization results of economic operations can be directly measured from the economic point of view.This paper presents a power grid analysis of economic operation. In the social context, through the power contribution of elastic coefficient, a unit of electricity adjusted GDP indicator to science provinces of electricity between the power supply; in the cost-effectiveness,through the purchase of the actual gross margin from electricity sales than planned gross margin from electricity sales to purchase incremental, that is super-plan benefits, the part regarded as a scheduling efficiency through the optimization of power grids run to obtain the economic dispatch efficiency, and its decomposition as "the purchase of many for sale"," reduce the power loss", "optimize the purchase of electricity" and "optimize the sale of electricity". China Power Grid of the numerical example to verify the validity of the method, and used to guide the work of power dispatching, analysis arranged, hydroelectric scheduling and backup support for other major economic events. Finally, this paper analyzes the impact of power grid and the risk of the economy.
