    MODELING OF OPERATIONAL ALGORITHMS FOR HYBRID PHOTOVOLTAIC/DIESEL GENERATOR/BATTERY SYSTEM
    (جامعة النجاح الوطنية, 2022-03-28) Adarba, Amjad
    Due to the fast increase of electrical demand and the high cost of electrical network infrastructure expansion in rural areas, a Hybrid PV/diesel generator/battery system is presented as an optimal solution because of its high reliability and low energy cost compared with other conventional energy sources. This thesis aims to obtain the optimum controlling dispatch-size strategy as per the requirements and concerns of the operating conditions, the used methodology in this thesis is to study, simulate, and summarize the main, three controlling dispatches with their operating strategies of hybrid PV/DG/Battery. While the overall optimal controlling dispatch-size strategy found in this thesis is Cycle Charge dispatch, for each requirement (reduction in PV-Battery size, reduction in a time when batteries at minimum state of charge, reduction in the diesel generator working minutes, reduction in the frequent switching between diesel and batteries, increasing sharing energy from renewable source, reduction in consumed fuel and reduction in unused excess energy percentage) an optimal controlling dispatch-size strategy can be obtained. The summery comparison results between different strategies is as the following: • Intuitive method simulation showed 59% of the consumed energy came from renewable parameters while 41% was generated from the diesel generator. 2800 minutes of the simulated time, batteries were at the minimum value of state of charge. 24% of the generated energy is considered as excess energy of the system and 328 Liters of fuel was consumed • Cycle Charge simulation showed 90% of the consumed energy came from renewable parameters while only 10% was generated from the diesel generator. Only 26 minutes of the simulated time, batteries were at the minimum value of state of charge. 35% of the generated energy is considered as excess energy of the system and 156 Liters of fuel was consumed Load Following simulation showed 73% of the consumed energy came from renewable parameters while 27% was generated from the diesel generator. 708 minutes of the simulated time, batteries were at the minimum value of state of charge. 71% of the generated energy is considered as excess energy of the system and 226 Liters of fuel was consumed.
