| Summary: | 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. |
