Generally due to the strategic equatorial region, Malaysia is advancing into solar energy as a replacement of alternative source for an electrical energy production to meet the escalation load demand. Thus, the integrated hybrid system like PVGenset set system are developed to generate power to meet load demand where it can be fitted into its local geography and others according to specification. However, this does not guarantee the hybrid system to generate power optimally as weather conditions (solar insolation, temperature and others) changes periodically and influence the power generation and the power dispatch to the load. Therefore, the hybrid system does not operate at the optimal state and without a proper dispatching controller it may lead to over stress one or the other hybrid system component causes frequent wear and tear with higher maintenance cost to the system. In order to curb this situation, the hybrid system requires a specific approach along with a controller to search and to dispatch the hybrid PV-Genset system generated power at the best potential optimal state. A Bio-Heuristic approach can be applied to determine the optimal power generation while a dispatch controller dispatches the electric hybrid power system to the load demand. The aim of this research is to implement the selected bio-heuristic approach such as Particle Swarm Optimisation (PSO) while Fuzzy Logic is used as a dispatch controller for a small scale hybrid PV-Genset system. The simulation of the hybrid PV-Gertset system modelling is simulated using two types of tropical weather conditions (sunny and rainy). From this research, simulation results are obtained and series of analysis is conducted using MATLAB/SlMULINK. Through the analysis, results have shown the contribution of each hybrid system component operates at the optimum level while power is dispatch to the load based on the hybrid system capability.
