Research on Grid-connected Strategy of Distributed Generation Dominated by On-grid Electricity Price (July 2018)

摘要

The access of high permeability and large-scale distributed generation makes the operating environment of distribution network extremely badly. To solve the problem of safe and reliable access to distribution networks with large-scale distributed energy sources, based on the on-grid price, this paper deduces the demand information of power distribution network by analyzing and comparing it; establishes the Markov decision process model, defines the reward and punishment mechanism of different behaviors; introduces particle swarm optimization algorithm to optimize the power flow calculation process and improve convergence rate; proposes the control strategy of distributed energy access to the distribution network, and maximizes the economic benefits of distributed energy under the premise of ensuring the highest priority of power quality, and provide more effective means to solve the problem of active distribution network dissipating distributed energy.
