System Stability Improvement of DG Connected to the Grid Based on Power Conversion and Energy Storage System
With people attaching importance to sustainable development and reducing environmental pollution, distributed generation technology is attracting more and more and more attention due to its unique environmental protection and economy. However, distributed generation will change with natural conditions so that it can not output power constantly and steadily, and most DGs are connected to the power system at distribution network side, this will cause system stability problem. In order to fully play the role of distributed power and avoid the adverse effects of its existence, a power conversion sand energy storage system to effectively regulate the system stability of distributed generation connected to the grid is presented. MATLAB/Simulink is used as a simulation and study tool in this paper, a system model of distributed generation connected to the grid is built and combined with actual operation in different environments to conduct real-time simulation analysis, the simulation results show that the power conversion system can enhance system stability of distributed generation connected to the grid.
