Optimal Design of Hybrid PV-Diesel - Battery System for a Small Cement Brick Factory: A Case Study for Bahteem, Egypt

This paper study the optimization & finical test of a hybrid power system holds Photovoltaic (PV) array, Diesel generator and Battery for a small cement bricks factory located in Bahtem, Egypt covering a load demand of 24.5kWh/day with a 4.92 kW peak. In this factory, light weight binder bricks are manufactured from the recycling of chopped grind straw which can be utilized as fillers in bone type buildings. HOMER software is utilized to run the frugal feasibility of hybrid PV-Diesel-Battery system. The study proved that the impact of PV penetration and battery storage on power production, expense of power, number of operational hours of diesel generators for a given hybrid configuration. PV panels and diesel generator produce 10,654 and 2,701 kWh/year, respectively and 2,783 kWh/year of power is stocked in the batteries. The renewable power part was 70%. The system was optimally sized with a PV of 7 kW, a diesel generator of 5.5 kW, a converter of 4.9 kW and 8 units of battery The obtained results showed that PV-Diesel-Battery system generates a great reduction in both the operating expenses the amount of CO2 and other greenhouse gases emissions.
