“…Similar to most remote rural areas, the residential units of the village require a low electricity supply for electrical appliances and lighting. Figure 3 shows the total daily load profile of the village's households [48]. A 5% random variability is considered for time step to time step and day-to-day analyses to provide better reliability.…”

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...

In this work, we focus on utilization of hybrid renewable energy system for a residential load based in two different optimisation criteria. The presented system utilises photovoltaic modules wind turbines and batteries as energy storage. The analyses were carried out based on experimental measurements, for the electrical load, local solar radiation, wind speed and other environmental parameters. The optimisation process has been performed based on two aspects economic and ecological. The novelty of this work to find the relationship between two optimisation objectives.

“…The HOMER software is used to study and design the proposed hybrid energy system model. Based on simulation results, it has been found that renewable energy sources perhaps replace the conventional energy sources and would be a feasible solution for the generation of electric power at remote locations with a reasonable investment [3]. Despite the comparatively high cost of electricity from distributed generation units, microgrids can be a valuable investment opportunity.…”

Microgrids are increasingly put forward as key concepts of future energy supply, complementing as well as transforming the conventional, centralized energy system. Here, the aim was to construct microgrid composed of wind and solar power plants, diesel generator and battery storage which will be independent of a large, centralized electricity grid and incorporate more than one type of power source so to supply Bjelimići area. This area is taken as a case study since it has large potential considering the renewable energy sources and because this feeder is quite long which makes energy losses considerably higher. All material which were used in this project consist of real network parameters which are provided by Public Electric Utility Elektroprivreda of Bosnia and Herzegovina. For completing the project, DIgSILENT PowerFactory software (base package and Quasi-Dynamic Simulation Toolbox), HOMER (Hybrid Optimization Model for Multiple Energy Resources) software and Microsoft Excel were used. System has been modeled using minimum total cost of investment as a goal for optimization function and to cover the maximum power load with battery storage and diesel generators. Therefore, appropriate installed power of wind, solar and diesel power plants in combination with battery storage, based on real energy resource data and real load profiles of existing customers, has been chosen. In the end, using obtained data from HOMER for model in DIgSILENT PowerFactory, power flow, voltage profiles, line and transformer loading, and total grid losses were analyzed. It has been concluded that microgrids should be considered as excellent solution for such and similar areas, especially when considering the construction or significant upgrading of networks. Also, results from DIgSILENT PowerFactory have proved that system can operate with modeled microgrid. In addition, it is shown that better conditions of the network are present when operated in the island mode.
