Abstract The distribution of electricity from State Electricity Enterprise does not necessarily reach remote areas, so these areas require alternative sources of electricity, such as solar power plants. This study aims to design and analyze the potential of small-scale off-grid PV in terms of engineering and economics. The research method has used a simulation on PVSyst software with four components, namely solar panels and batteries. The research results were obtained based on four variations made: a 700Wp panel, a 24V 150Ah battery, and an 800W inverter. The design will produce electrical energy of 2 kWh/kWp/day with a total investment value of IDR 54,268,068 for a project period of 24 years. Compared to using a one kVA generator, the investment value was approximately IDR 208,575,063 for a 24-year project. Compared to batteries with the same specifications using a State Electricity Enterprise electricity charging source, the investment value for a 24-year project was IDR 81,036,162. NPV values in all variations obtained < 0, and PBP > the system project period. Thus, this system was considered not economically feasible and did not provide profit. Still, the off-grid solar power plant option was the most profitable than generators or battery power sources with State Electricity Enterprise charging.

After the expiration of governmental incentive measures for renewable energy sources integration, economic feasibility of investing into solar power plants will highly depend on compatibility between production and variable prices. In order to achieve the maximum possible profit of the power plant in liberalized electricity market, it is necessary to consider the possibility of investing in solutions that are not common today, but with the potential of being more profitable in the future. Such a solution is a solar power plant consisting of vertically placed bifacial modules whose active surfaces are oriented in the east-west direction. This configuration of the power plant can achieve higher production in periods of high prices, and thus higher profits from the sale of electricity. On the other hand, such a solution is more expensive than a standard solar power plant with monofacial modules. In this paper, a comparison of return on investment in a bifacial power plant and a monofacial power plant with existing and prospective market conditions is performed. The influence of solar power plant production on the price of electricity was investigated on the example of Germany. Based on this research, a prognostic model of the daily price diagram on the unified European market until 2040 was formed. It served for the analysis of the profitability of investments in the two considered variants of the solar power plant realization.

Vietnam is a country of a great solar potential; solar technology is growing rapidly in Vietnam and investors are very interested in building solar power plants. Construction of the rooftop solar power stations can help owners reduce monthly electricity costs and even get economic benefits by selling excess electricity coming from a solar power plant (PV) to the utility grid. In this study, the design results of a rooftop grid-tied solar power station with the capacity of 26 kWp for a commercial building were introduced to have a basis to assess the operation ability of solar power station under solar radiation conditions in Hanoi city, Vietnam. The simulation results using the PVsyst program have made it possible to calculate the solar energy potential in Hanoi city, the power generation and efficiency of the grid-tied solar power station. Solar power has been applied in Vietnam since the 1990s but is mainly used for areas that were far from national power grid such as mountainous areas, islands. Small scale grid-tied solar power has been developed since 2010 and mainly is used for residential applications or small and medium scale consumers. The total capacity of electricity produced by solar power plants in Vietnam by 2017 was only about 8 MW; this value is very low as compared to the potential of solar power in Vietnam. This is due to the absence of the government support for the policy of developing solar power. In accordance with the current roadmap of raising electricity prices in Vietnam, construction investment of rooftop solar power stations is economically feasible while contributing to environmental protection and counteracting climate change phenomenon by reducing the amount of CO2 emitted into the environment.

There is great potential for generating solar energy using unused space on roofs and vacant lots around buildings. Small amounts of energy generated by each individual household, industrial building, commercial building, or any other type of building can be used to partially meet the needs of the building's residents, and the surplus, if any, can be fed to the grid. To use the existing roof space of buildings, SPV systems on the roof of buildings can be installed to replace DG generators installed to provide the minimum load required to operate during load shedding. TSTU has a large unused roof area from both residential and office buildings. Therefore, it has a huge potential for generating solar energy by installing a grid-connected Solar system on the roof. We can reduce a large amount of bills by implementing a solar power plant. The government has also launched various solar energy incentive schemes, this article provides a brief overview of rooftop photovoltaic and small-scale solar generation systems, and discusses various government schemes. Since TSTU has a large scope for this scheme, so the calculation of the design capacity was made for the technological College and one residential building. A method has been developed for calculating the capacity of Autonomous solar power plants and its elements, which allows us to take into account changes in the load during the day and thereby accurately determine the required capacity of the battery and eliminate unjustified overestimation of the power of power plant elements and increase the cost of the Autonomous solar power plant itself.

Combined Operation

In view of the dependence of power generation at photovoltaic solar power plants on the level of intensity of solar radiation and cloud cover, their operation creates a number of problems in the power system. This article describes the problems of operation of such power plants of non-guaranteed capacity during their parallel operation as a part of the Unified Energy System of Ukraine. One of the measures of stabilizing the operation of power plants of non-guaranteed capacity is the use of systems of electric energy storage. The article describes the conditions of electrical connection, which ensure the possibility of combined operation of a system of electric energy storage and a photovoltaic solar power plant. The article presents the developed mathematical model of the combined operation of a photovoltaic solar power plant (PSPP) and a system of electric energy storage. We consider the daily mode of recharging from a PSPP and discharging batteries into the power system in order to preserve the excess of generated electricity at the PSPP, which earlier was lost due to the restriction on inverters caused by the overload with photovoltaic power. The model enables one to identify the key parameters of batteries – power and capacity, taking into account the physical and technical features of the operation of battery storage as to the conversion efficiency, the number of working cycles and the depth of possible discharge depending on the structure of PSPP equipment and solar radiation intensity. Using the developed model, we determined the values of power, charging and discharging capacities of a lithium-ion system for storing electrical energy, when it works together with a 10 MWAC photovoltaic solar power plant at different overload factors. The article presents some results of technical and economic assessment of the combined operation of a PSPP and a lithium-ion system for storing electrical energy. The results showed an increase in the power and capacity of a storage device with increase in the overload factor of PSPP, which leads to the growth of cost of electrical energy at their combined work. At the same time, the amounts and quality of electricity supplied increase.
