Method for evaluating new energy development potential of regional power grids based on power generation absorption

Abstract

The invention relates to a method for evaluating the new energy development potential of regional power grids based on power generation absorption. New energy power characteristics are described from the level of new energy output power parameters, and power grid structure constraints are described from the level of power grid load flow calculation parameters. Based on a sequential production simulation method, by establishing a multi-period load flow optimization evaluation model and adopting matlab software for programming simulation calculation, a corresponding new energy receptivity evaluation model is established with the power generation of new energy units as the objective function and the new energy wind curtailment/light curtailment rate as the constraint. The new energy development degree of the regional power grids is comprehensively measured, visual development potential measurement indexes are obtained finally, and the new energy receptivity trend of the regional power grids is analyzed in a drawing mode. The power generation of the power grids by renewable energy absorption is simply and visually calculated, and reasons for the insufficient new energy receptivity of the power grids are analyzed. The economy and safety of power grid operation are analyzed based on various operation scenes, and the new energy receptivity of the power grids under various scenes is studied.

Description

technical field [0001] The invention relates to an energy management technology, in particular to a method for evaluating the development potential of new energy in a regional power grid based on electricity consumption. Background technique [0002] With the economic development of countries around the world, the world's energy demand is increasing, and the demand for electricity is the most significant. In today's world, traditional fossil energy such as coal, oil, and natural gas still occupy a dominant position, and with the development and utilization of fossil energy, the earth on which human beings depend is facing environmental degradation, resource shortage, severe smog, and greenhouse effect. question. The limitations of fossil energy have broken the coupling relationship between energy development and economic growth. The environmental degradation and energy shortage caused by the massive development of traditional energy have hindered the safe, efficient and sus...
