Malaysia is advancing into solar energy as a replacement of alternative source of an electrical energy production to meet the escalation load demand due to the strategic equatorial region. Hybrid PV-Genset system are developed to generate power as it can be fitted into its local geography and other condition according to specification. However, this does not guarantee that the hybrid system generates power optimally because weather conditions (solar insolation, temperature and others) changes periodically and influences the power generation and dispatch. Therefore, under these circumstances the hybrid system does not operate optimally and lead to over stress the system components resulting a higher maintenance cost due to frequent wear and tear. Particle Swarm Optimisation (PSO) is implemented into two non-linear optimisation areas such as the PV power tracker system and the power dispatch controller. The required bio-inspired algorithm searches the best potential optimal state for the maximum PV power generation as well as determining the suitable power dispatch arrangement of the small scale hybrid PV-Genset system. Fuzzy Logic Controller (FLC) and logic gate are used as a battery monitor for the power dispatch controller depending on the capability and availability. The hybrid PV-Genset system modelling was simulated using two types of tropical weather conditions (sunny and rainy). As an outcome, the obtained simulation results and series of analysis are conducted using MATLAB/SIMULINK environment. Through the analysis and results, the contribution of each hybrid system component operates at the optimum level and hybrid power is dispatch to the load based on the hybrid PV-Genset system capability.
