A Study on Micro-Grid Power Quality Management and Simulation Based on RTW Toolkit

For improving micro-grid power quality, this paper elaborates a method of using energy storage system to stabilize power and active power filter (APF) to govern harmonic. The control principle of energy storage system and APF is introduced, and the simulation model of the micro-grid is established, which can generate C code automatically through MATLAB real-time code generation tool RTW (Real-Time Workshop). The code is applied to the running real micro-grid system. By comparing APF simulation results and actual running results, the effectiveness and practicability of the simulation based on RTW were verified. At the same time, it shows that the application of APF has a positive role in micro-grid power quality improvement.
