The problem with the condition of the Solar Power Plant is still not optimal due to position of the solar cells in generator is still static so that absorption of light is still not even though Hybrid technology is now available but cannot be optimized properly and still cannot be optimized implemented especially in small scale and remote areas. Another problem that needs attention is the continued operation of installed Solar Power Plants (SPPs), considering the installation and maintenance of the plant requires high investment costs because the installation of solar panels requires a large amount of land and costs besides requiring qualified technical personnel to handle problems and monitoring plant conditions are needed quickly and accurately. From the description of the problem, the first step is to identify the technology used in the factory, the second is the need to design a new system to be able to solve important problems in the plant and the third is to build a computerized system that uses the Hybrid Method on the plant used. is a combination of Artificial Intelligence and Data Mining Processes so that it can present accurate data so that it can help and analyze plant performance, monitor and control plants remotely quickly by using Web Control.

The abandonment of conventional sources in favor of energy from renewable energy sources (RES) has a global dimension, and the dynamic increase in the share of energy from photovoltaic systems in the energy mix of many countries results from the possibility of obtaining it both on a small scale (micro-installations) and as part of economic investments (photovoltaic power plants). The study aimed to assess the economic efficiency of 22 photovoltaic farms located in northeastern Poland. The research covered 5 solar power plants with a capacity of up to 799 kWp (I), 13 between 800 and 1100 kWp (II), and 4 installations of 1.98 MWp (III). The evaluation was based on net present value (NPV), internal rate of return (IRR), payback period (PP), profitability index (PI), accounting rate of return (ARR). Additionally, a sensitivity analysis was carried out regarding the value of economic indicators. The analysis shows that all studied PV farms are economically justified investments (NPV > 0) regardless of the adopted scenario. Solar power plants of the largest analyzed capacity (group III) resulted in being the most profitable ones, but no linear relationship between the level of productivity and profitability was established. Due to the large variation in terrain shape in northeastern Poland, landscape value and social benefits, which are difficult to assess, the support system for investments regarding the construction of photovoltaic power plants proved to be the most effective in group I.

ABSTRAK Paper ini membahas tentang simulasi dan pembuatan rangkaian sistem kontrol pengisian baterai yang bersumber dari sebuah pembangkit listrik tenaga surya (Panel Surya). Pengisian baterai yang terlalu lama pada sebuah instalasi pembangkit listrik tenaga surya akan menyebabkan baterai cepat rusak sehingga dibutuhkan sebuah sistem yang dapat berfungsi sebagai pengontrol. Metode penelitian yang dilakukan yaitu dengan merangkai rangkaian yang didapat dari pustaka kemudian disimulasikan dengan perangkat lunak Proteus ISIS Profesional, selanjutnya dilakukan pembuatan rangkaian elektronika dalam sebuah PCB. Tegangan yang dihasilkan oleh baterai dibaca oleh sistem kontrol kemudian sistem akan memilih apabila tegangan yang diberikan oleh panel surya akan diisi pada baterai atau dialihkan kepada sebuah beban tambahan. Hasil yang didapatkan dalam penelitian menunjukan bahwa sistem kontrol pengisian baterai yang dibangun telah bekerja sesuai dengan simulasi dan dapat bekerja dengan baik. Kata-kata kunci: sistem kontrol baterai, switch, panel surya. SIMULATION AND CONSTRUCTION OF A BATTERY CHARGING CONTROLLER SYSTEM FOR SOLAR POWER PLANTS ABSTRACT This paper discusses about circuit simulation and construction of a battery charging control system from a solar power plant (Solar Panels). Charging the battery for too long on an installation of solar power plants will cause the battery to be broken and so we need a system that can function as a controller. The research method is made by simulating a baterry charging control circuit from a reference and then simulated by Proteus ISIS Professional software, then constructing the circuit on a PCB. The voltage produced by the solar panel is read by the control system then the system will prefer if the voltage supplied by the solar panels will be filled on the battery or transferred to an additional load. Result obtained in this study indicate that the baterry charging control system are working in accordance with the software simulation and can work as a baterry charging control system for a solar panel instalation. Keywords: Baterry charging control, switch, solar panel.

Abstract A solution for automated monitoring and diagnostics of photovoltaic modules of industrial solar power plants is proposed. The solution is based on the use of an unmanned aerial vehicle with a specialized payload and a ground-based intelligent information and control system to detect problem areas of the station, in particular partial shading and pollution. To perform the detection procedures, a neural network based on the Fast R-CNN architecture with the learning algorithm – Inception v2 (COCO) was used. The results of preliminary tests showed that the accuracy of detecting problem areas is at least 92%. The article presents a mathematical model that allows calculating the installed power monitored by the complex, depending on the type of station and UAV, meteorological parameters, and the performance of computing equipment. Numerical calculations have shown that when using the FIMI X8SE UAV and a computing device based on the RTX2080 GPU, the installed monitored power will be up to 7.5 MW.

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.
