Abstract
In allusion to problems such as complicated system structures,difficult control and management,being unfavor-able to coordinated optimization,difficulty in plug and play due to distributed generations (DGs)in traditional micro-grid u-sing respective grid-connected converters to access to the power distribution networks,this paper proposes a kind of energy local network framework for DGs,energy storage devices and loads accessing to the system via AC/DC interface provided by the solid state transformer (SST).It uses the designed SST and control strategies of DGs and energy storage to study coordi-nated operation of the energy local network so as to keep the bus voltage constant and ensure normal power supply of impor-tant loads. Meanwhile,it considers two operation modes including grid-connection and island and designs four working modes to make simulation on operation of the energy local network under different operational conditions and transient process based on MATLAB/Simulink.Simulation results indicate the proposed control strategy can reduce fluctuation of out-put power of high permeability renewable energy and voltage fluctuation caused by load variation and stabilize bus voltage, which verifies feasibility and effectiveness of the strategy.关键词
