What are the major impacts that results from connecting different renewable energy source to the grid on both grid connected mode and island mode?
describe the operation of connecting different renewable energy source to the grid
one of the most valuable papers is " A novel control strategy for grid connected hybrid renewable energy systems using improved particle swarm optimization "
proposes a novel hybrid centralized and distributed control of hybrid renewable energy system consisting of AC/DC micro grids. An Interlinking Converter (IC) is used to connect both sides of the micro grid systems together. Improved Particle Swarm Optimization (IPSO) which acts as a master controller is used to control the power of the sources based on IC control. Also, there are different slave controllers for 100 kW photovoltaic, fuel cells and 100 kW wind, which are designed to supply continuous load power. Coordination between two grids is satisfied through droop control for both AC and DC micro grids to achieve power sharing process and control of renewable energy sources supplying different loads. The model has been implemented in MATLAB/SIMULINK. The proposed controller succeeded to manage energy between micro grids under different scenarios. The control technique using IPSO strategy improves the dynamics of the hybrid system connected to the grid.
