Operation control of photovoltaic/diesel hybrid generating system considering fluctuation of solar radiation

Feasibility study of hybrid Diesel–PV power plants in the southern of Algeria: Case study on AFRA power plant

“…i = 1 in inverter mode and 2 in charger mode. The operating cost of a diesel generator is governed by its fuel consumption, while the maintenance cost depends strongly on the number of operating hours and the loading of the engine [2]. We assume that the hourly fuel consumption Consu fuel is a function of a power called P DG [12,36]:…”

“…Nevertheless, diesel generators are inherently inefficient when operated at a low load factor (below 40-50% of their rated capacity), which can also shorten their operating life and result in high maintenance costs. Low combustion temperatures during periods of operation with light loads cause incomplete combustion and carbon deposits on the cylinder walls, leading to premature engine wear [1,2]. Such situation makes these power plants uncompetitive.…”

“…In the literature, several hybrid systems are described, such as PV/Diesel generator power systems without storage [13], PV/Battery/Diesel [2,14,15], PV/Wind Turbine/Battery [16][17][18], PV/Wind Turbine/Battery/Diesel [19], PV/Wind/Diesel without storage [20], PV/Wind only [21], PV/Wind/Diesel/Microhydroelectric turbine [22] and PV/Wind/Fuel cell [23]. The selection process for hybrid power sources at a given site is dependent on a combination of many factors, including the load demand, site topography, seasonal availability of energy sources, cost of energy storage and delivery, seasonal energy requirements, etc.…”

An optimized Fuzzy Logic Controller by Water Cycle Algorithm for power management of Stand-alone Hybrid Green Power generation

“…In addition to the SHGP, it is well known that energy storage like battery and super capacitor used as an auxiliary power resource provides additional advantages such as stability, power quality and reliability. There are several configurations of SHGP described in the literature, such as photovoltaic (PV)/diesel generator power systems [4], PV/battery and diesel [5][6][7], PV/wind turbine and diesel [8], PV/wind only [9], and PV/wind/diesel/micro hydroelectric turbine [10]. Optimization of a hybrid system consists of two parts: first, the component sizing and second, the energy dispatch strategy.…”

Performance Evaluation of a Control Strategy Developed for a Hybrid Energy System Integrated in DC-AC Microgrids

“…Bonanno and Patani [7] proposed a fuzzy logic approach to address the energy flows management (EFM) problems in integrated generation systems. Park et al [8] proposed an operation control of a solar-PV/diesel hybrid generating system for a small ship in consideration of the fluctuating solar-PV power due to solar radiation. The aim of the control is to minimize the fuel consumption and storage capacity of the battery.…”
