In recent years, the concept of hybrid energy systems (HESs) is drawing more attention for electrification of isolated or energy-deficient areas. When optimally designed, HESs prove to be more reliable and economical than single energy source systems. This study examines the feasibility of a combined dispatch (CD) control strategy for a photovoltaic (PV)/diesel/battery HES by combining the load following (LF) strategy and cycle charging (CC) strategy. HOMER software is used as a tool for optimization analysis by investigating the techno-economic and environmental performance of the proposed system under the LF strategy, CC strategy, and combined dispatch CD strategy. The simulation results reveal that the CD strategy has a net present cost (NPC) and cost of energy (COE) values of $110,191 and $0.21/kWh, which are 20.6% and 4.8% lower than those of systems utilizing the LF and CC strategies, respectively. From an environmental point of view, the CD strategy also offers the best performance, with CO 2 emissions of 27,678 kg/year. Moreover, the results show that variations in critical parameters, such as battery minimum state of charge, time step, solar radiation, diesel price, and load growth, exert considerable effects on the performance of the proposed system.

Sustainability 2019, 11, 683 3 of 26Although the non-dispatchable RESs necessitate complex systems modeling, they are themselves simple to model without the need for control logic, in which the power is merely produced in direct response to the available renewable energy resources. On the other hand, the dispatchable components, such as the generator and battery, are more difficult to model because they must be controlled to achieve matching of demand and supply properly, and to compensate for the intermittency of the non-dispatchable RESs [16,17]. "Should a generator charge the battery or should excess solar production be responsible for charging the battery only and the generator used only to satisfy the load?" This question has led to some rules that manage the operation of generator and battery energy storage. The load following (LF) and cycle charging (CC) dispatch strategies are used to control generator operation and battery energy storage. Under the LF strategy, a generator produces only e...

“…The renewable fraction in this case was 0.98. Conversely, at a site in Puerto Estrella with a load of 379kWh/day (88kW peak), the optimum composition of the hybrid system was found to be "500 PV panels (320 W each), 1 Aeolos 10 kW wind turbine, diesel generator of 25 kW, 250 Surrette batteries s4ks25p, and inverter of 80 kW" [32]. While this system includes a portion of wind power generation, the bulk of the load is still covered by the Solar PV array.…”

Increased implementation of renewable technology for power generation is critical to achieving the emissions targets set by many countries, as well as delivering an economically viable method of providing power to isolated communities. This project set out to analyse and compare three technologies, namely Solar PV, Concentrating Solar Thermal with thermal storage and diesel generators, for deployment in remote Australian areas. In this paper, a detailed literature review of past projects involving renewable energy hybrid power generation systems has been completed. Thirty-six sources were chosen for the review based on criteria of recentness, relevance and peer review. Using these sources, this review has identified key areas of focus in the subsequent analysis as being the inclusion of solar thermal with thermal storage and a life-cycle analysis of GHG (embodied and emitted) and demonstrated the technical, economic and environmental feasibility of implementing hybrid energy systems worldwide and in Australia.The information presented in the literature review has been used to guide the creation of an analysis code in the Python software package which analyses supplied weather and electric load data and identifies the optimum mixture of technologies in the hybrid system. The results of this analysis have shown that Port Augusta is the ideal site for implementation, with an optimum system containing 89% Concentrating Solar Thermal, 9% Diesel and 2% Solar PV and a total installed power of 8.9MW. This system has an LCOE of $0.203/kWh, a renewable fraction of 92% and results in an annual CO 2 reduction from a 100% diesel system of 13,412,749kgeqCO 2 .Final Report -ENGG7280 4 17/06/2017It is recommended for future projects in this area that weather and electric load data be gathered over several years at each site under analysis, preferably over the same period to allow for more accurate comparison. It may also be worthwhile to broaden the scope of future reviews to include wind turbines and battery technology in the analysis.

The There are many factors influencing the performance of photovoltaic (PV) systems. Among these factors, temperature and solar radiation are two major parameters that have a large effect on the efficiency of PV systems. The cell temperature of PV panels is related to the ambient temperature while the solar radiation incident on the surface of the PV modules depends on the slope and azimuth of these modules. Furthermore, ground reflectance (albedo) affects the irradiance incident on the PV panel surface, which in turn affects the output of a PV system. Nevertheless, the effects of these factors on the economic performance of the solar PV systems are scarcely reported. This paper presents a complete design of a stand-alone PV/battery system to supply electric power for a mobile base station in Choman, Erbil, Iraq. The effects of different factors on the total electricity produced by PV arrays and its economic performance are simultaneously investigated. HOMER software has been used as a tool for the techno-economic and environmental analysis. As indicated from the simulation results, the PV array capacity and its economic performance are highly affected by the variation of the slope and azimuth. With a base case (albedo of 20% and average annual ambient temperature of 11°C), the best feasible system which is achieved by facing PV due to south with a tilt angle of 40° or 45°, is found to have net present cost (NPC) of 70595 $ and cost of energy (COE) of 0.54 $/kWh. Moreover, the results indicate that increasing the ground reflectance from 10% to 90% results in a 7.2% decrease in the PV array capacity and about 3% decrease in the NPC and COE. On the other hand, increasing the ambient temperature from 0°C to 40°C results in a 19.7% increase in the PV array capacity and an 8.2% increase in the NPC and COE. Furthermore, according to the ambient temperature of Choman, using PV modules with high sensitivity to temperature is found to be an attractive option. Provided simulation performance analysis proves that the studied parameters must be treated well to establish an enabling environment for solar energy development in Iraq.
