Purpose This study aims to investigate the feasibility of proposed microgrid (MG) that comprises photovoltaic, wind turbines, battery energy storage and diesel generator to supply a residential building in Grindelwald which is chosen as the test location. Design/methodology/approach Three operational configurations were used to run the proposed MG. In the first configuration, the electric energy can be vended and procured utterly between the main-grid and MG. In the second configuration, the energy trade was performed within 15 kWh as the maximum allowable limit of energy to purchase and sell. In the third configuration, the system performance in the stand-alone operation mode was investigated. A whale optimization technique is used to determine the optimal size of MG in all proposed configurations. The cost of energy (COE) and other measures are used to evaluate the system performance. Findings The obtained results revealed that the first configuration is the most beneficial with COE of 0.253$/KWh and reliable 100%. Furthermore, the whale optimization algorithm is sufficiently feasible as compared to other techniques to apply in the applications of MG. Originality/value The value of the proposed research is to investigate to what extend the integration between MG and main-grid is beneficial economically and technically. As opposed to previous research studies that have focused predominantly only on the optimal size of MG.

“…Currently, the most widely used renewable energy source is solar energy-it is safe, clean and easy to use, therefore it has become one of the most suitable energy sources that can be used in various fields and can be an alternative to fossil energy sources [18][19][20][21][22]. Many studies offer mobile PV systems solutions for autonomous electricity generation [23][24][25][26]. With regard to temporary shelters, electricity is usually provided by off-grid solutions (diesel fuel generators), which are not a sustainable energy supply because of their dependence on fuel availability.…”

Mobile Off-Grid Energy Generation Unit for Temporary Energy Supply

et al. 2022

Temporary structures are being extensively used by emergency services (rescue, disaster relief, military response units), and other end-users requiring temporary mobile off-grid energy solutions for different purposes (event organization, vacation homes, summer camps, etc.). Yet energy systems for these purposes largely remain fossil-based (such as diesel generators). Although such energy systems are inexpensive, they are carbon intensive and inefficient. This study presents a methodology of simulating temporary shelter with access to an energy supply system through a mobile energy unit with renewable (PV) power supply systems to ensure on-site electricity production, as well as heating/cooling and ventilation. Digital modeling simulations have been performed for a simulated temporary shelter in different climate conditions incorporating different combinations of electricity generation systems with a fossil fuel-based solution and a PV system, using TRNSYS software. Study results show that the operation of a mobile energy generation unit can operate HVAC systems and generate electricity for temporary shelter occupants in off-grid solutions. The modeling results show that the use of a mobile energy generation unit can significantly reduce diesel consumption in temporary shelters from 54% annually (in Riga, Latvia) to 96 % annually (in Jerusalem, Israel). Furthermore, the output of PV-generated electricity is higher (in most cases) than the consumed electricity amount.

“…On the other hand, diesel generators have a lower initial cost but higher fuel and maintenance costs. Offgrid PV systems are widely promoted for use in rural areas to generate cleaner, safer, and more reliable energy [26], [27]. Nowadays, hybrid system installation is completed quickly and easily.…”

This paper aims to optimize the power system design of a vineyard house in Pazarcık, Kahramanmaras. In this process, the electrical energy demand is met by the hybrid Photovoltaic-Wind-Diesel-Battery system because the vineyard house is remote from the electric network. The vineyard house is located in Karagol, southern of Pazarcık. During the summer in Karagol, many people stay in and visit the vineyard houses. However, the vineyard houses are generally unoccupied in winter. Therefore, an economical energy source is required in this process without compromising life quality. Capital costs are high and the running costs are low for stand-alone renewable sources. On the other hand, it is the opposite for stand-alone diesel power generators. This study is designed to take these circumstances into consideration. The optimal design is investigated for a hybrid system of renewable energy sources and a diesel power generator. The Homer software is used during this process. The realized design is evaluated in terms of its technical and environmental aspects. As a result of the study, 6 kW photovoltaic panels, a 1 kW wind turbine, a 1 kW diesel generator, a 2 kW converter, and an optimally sized 8-unit battery system are used to meet the electricity needs of the vineyard house. The renewable energy factor is 99.8% for a vineyard house. This value is an acceptable rate for a net zero energy house. This study shows that the hybrid system meets the house's electric energy demands and has a positive impact on the environment by reducing greenhouse gas emissions.
