local.description.resumoThis paper presents design steps of a distributed generation system with load power compensation. A single-phase full-bridge converter is used to connect the alternative source to the mains. Besides injecting active power, the distributed generation also provides load power compensation capability. In this context, a current reference strategy based on single-phase circuit theory is proposed for grid-connected multi-task converters. The main idea is to synthesize the signal reference for control loop generating orthogonal signals from grid voltage and current load. A Third Order Sinusoidal Integrator is used to extract fundamental component and generate the orthogonal waveforms of grid voltage and load current. Current controller loop for interface converter is developed based on Linear Quadratic Regulator theory. Simulation results are presented to verify the system behavior.
