The invention discloses a new energy system capacity configuration method and device and a regional power grid system. The new energy system capacity configuration method comprises the following steps: establishing an individual gene sequence according to a regional power grid frame topological structure; wherein the individual gene sequence is the sequence of each load branch connected with each regional net rack main path in the region, and the new energy configuration capacity of a new energy power generation branch in the load branch is used as an individual gene; generating a plurality of populations; the population comprises a plurality of individuals, and individual gene sequences after gene assignment are taken as individuals; performing optimization calculation on the plurality of populations according to environmental constraint conditions and the predicted power trajectory of each load branch of each individual in a preset time period to obtain a plurality of target individuals; and selecting a configuration capacity result of one target individual as a new energy system capacity configuration scheme in the regional power grid. According to the invention, from the global perspective of the region, the regional cooperative control consumption is considered, and the capacity planning problem of the new energy system of each region is solved.
Description
technical field [0001] The invention relates to the technical field of new energy, in particular to a method and device for capacity configuration of a new energy system, and a regional power grid system. Background technique [0002] At present, the problem of global energy shortage and environmental pollution is becoming more and more serious. With the development of the energy revolution, the proportion of clean energy (such as wind power and photovoltaic power) used in the load becomes more and more important. However, the power consumption scenarios of different regions in the same region are different, and the load in different regions may have the following gaps: large difference in peak-to-valley power consumption, large dynamic fluctuation of power consumption, periodic fluctuation of power consumption, and power demand in different time periods. Large difference in volume, uncertainty of capacity expansion and expansion of original load, etc. [0003] The above fa...
