Abstract

The invention relates to a novel town peak clipping and valley filling double-layer optimization operation method considering participation of electric vehicles in a park, and belongs to the technical field of energy system operation optimization, and the method comprises the following steps: S1, building a novel town double-layer optimization scheduling model under peak clipping and valley filling optimization; s2, initializing parameters, and determining an objective function and constraint conditions of an upper-layer optimization scheduling model; s3, using a CPLEX solver to solve the upper layer optimization scheduling model; s4, outputting a solving result of the upper-layer optimization scheduling model, and determining a peak clipping and valley filling target distribution value of the lower-layer park according to a feedback result of the lower-layer park; s4, determining an objective function and a constraint condition of the lower-layer optimization scheduling model; s5, solving a lower-layer optimization scheduling model by using a chaos dragonfly algorithm; s6, outputting an optimal scheduling strategy, and feeding back a result to an upper town; s7, judging whether the novel town double-layer optimization model under the peak clipping and valley filling optimization meets a termination condition or not, and if yes, outputting a result; otherwise, returning to S1.

Description

technical field [0001] The invention belongs to the technical field of energy system operation optimization, and relates to a two-layer optimization operation method considering the participation of electric vehicles in parks in new urban peak shaving and valley filling. Background technique [0002] The intermittent and anti-peak regulation characteristics of wind power and photovoltaics make it difficult for them to be completely absorbed. At present, the curtailment of wind and solar power is serious. Wind power also indirectly increases the load peak-to-valley difference, which increases the difficulty of peak regulation and frequency regulation of the system, and ensures the safety and stability of urban power grids. Threats to run. As the main consumption terminals of photovoltaics and wind power, cities and towns not only have to bear the uncertainty of the output of intermittent energy such as wind power and photovoltaics, but also need to take into account the rando...
