Abstract

Microgrids have become very popular over the past decades due to increase in use of distributed energy sources. Microgrids can be very useful to provide power in rural areas. The power switch to control across the hybrid microgrid is a vital aspect to pick up benefits. There are various techniques anticipated to control the power flow; however, majority of these techniques make use of proportional integral controllers, but due to its drawback of slow response and difficulty to tune, several innovative methods have been developed, which eliminate the drawbacks of existing control solutions. One of them is the hill climbing power flow algorithm, which uses perturbations of the power angle and observation of change in active power. Yet, this method is applied in a simple system; thus to check its feasibility and synchronism with other controllers, a complex hybrid microgrid model is proposed. In this paper, a generalized model of hybrid microgrid, consist AC microgrid, DC microgrid and main grid, presented, which including hill climb power flow control algorithm to manage power sharing between AC and DC microgrids, and a generalized MATLAB function has been generated to manage power flow from main grid. Simulation results are presented with different loading conditions. The model is implemented and tested in MATLAB/Simulink®.
