Optimal photovoltaic system sizing of a hybrid diesel PV system

Abstract EN

This paper presents a cost analysis study of a hybrid diesel and Photovoltaic (PV) system in Kuala Terengganu, Malaysia.

It first presents the climate conditions of the city followed by the load profile of a 2MVA network; the system was evaluated as a standalone system.

Diesel generator rating was considered such that it follows ISO 8528.

The maximum size of the PV system was selected such that its penetration would not exceed 25%.

Several sizes were considered but the 400kWp system was found to be the most cost efficient.

Cost estimation was done using Hybrid Optimization Model for Electric Renewable (HOMER).

Based on the simulation results, the climate conditions and the NEC 960, the numbers of the maximum and minimum series modules were suggested as well as the maximum number of the parallel strings
