英文摘要：

It is of significance for enhancing energy-saving and economy of power system and reducing the carbon-emission intensity to argue the power system planning scheme and to optimize its operating modes under complex generation and transmission structure. A low-carbon oriented analysis and evaluation technique for power system energy-saving and economic operation is proposed and corresponding software is developed. Taking power system operational simulation technology as the core, based on time sequence load curve and considering the security constrained unit commitment coordinated with multi-types of power sources, the energy-saving and economic operation evaluation system implements the day-by-day refined operation simulation of power grid in a whole year, on this basis multidimensional evaluation indices such as operation cost, energy consumption, carbon emission and power system efficiency are constructed to realize multidimensional evaluation of power grid energy-saving and economic operation. The architecture, data structure, functional sub-modules and the presentation interface of the evaluation results are designed. Based on the planning data of South China power grid, the empirical analysis on the economy and energy-saving performance of five provinces in South China before and after the grid-connection of new energy is performed.
