Investigation on Electronically Coupled Distributed Generation Modeling and Control Strategies for Microgrid Applications

A single-stage power converter capable of both maximum power point tracking and unity power factor dispatching is proposed for electronically coupled dispersed generation. Modeling a solar array (the dispersed generator) and a three-phase grid-connected inverter yields the best control parameters. Inner and outer control loops are used by the inverter’s controller to control parameters. The inner control loop translates input from the abc frame to the d, q, 0 frame in order to dispatch at unity power factor. The new technique, which may be used at the primary control level in microgrid applications, tracks the maximum power point in the outside circuit. loop of voltage control (local controller). The active power of single-stage and two-stage power converters is compared, revealing that single-stage is more efficient. In terms of active power yields, a comparison is made between variable and fixed DC reference voltages for the proposed single-stage converter system. The impacts of diverse ambient disturbances on active and reactive power yields, such as changing weather conditions, solar radiation with severe disturbances, and varying PV cell temperature, are explored in this paper. this project A dynamic reference voltage is advised for use. Simulations in Matlab/Simulink demonstrate its efficiency under a variety of radiation and temperature settings. The single-stage power conversion system executes all duties correctly with a unity power factor operation.
