Considering the impact of across provincial and regional transaction on flexible resource allocation and the frequency regulation demand due to large-scale renewable energy grid connection at the sending end

the flexible coordinated operation scheme across province and region considering the frequency regulation demand is proposed. In order to improve the frequency response capability of large-scale renewable energy access system

the operation scheduling scheme considers the generation uncertainty in the sending end system and the frequency modulation demand. The virtual power plant is introduced into the receiving end system for centralized management and optimization of flexible resource scheduling. In view of the feature of high latitude

strong coupling

non-linearity and non-convex

a kind of multi-objective double population pseudo parallel evolutionary algorithm is proposed for calculation. Finally

the quantitative analysis of the economy and pollution emission of the across the provincial system is performed through the calculation example analysis so to provide technical support for the suitability of across provincial and region channel to transport high proportion of renewable energy in the future.
