ABSTRACT Renewable energy is potential alternative energy to replace the central role of fossil energy which has been going on since the early 20th century. The solar power plant is alternative energy, especially for households and industry, and can be designed as a hybrid power plant consisting of solar panels, batteries, an automatic transfer switch (ATS), and a grid. This research will focus on developing ATS based on a microcontroller. It functions to regulate the load supply automatically from the three sources of electrical energy, like solar panels, batteries, and grid while the microcontroller functions to monitor the transfer of power from the solar power plant to grid and voltage movements in the system so that current and voltage data can be recorded from time to time to improve system reliability, effectiveness, and efficiency of the tool. ATS components consist of MCB, magnetic contactor, timer H3CR, relay, 2000VA inverter, solar charge controller 100A, NodeMCU ESP8266 IoT, and battery 12V 100AH. This research is conducted in one year to produce ATS based on a microcontroller that can automatically regulate the supply of loads from the three sources of electrical energy with a good level of efficiency and stability.  Keywords: solar power plants, hybrid power plants, an automatic transfer switch.  ABSTRAK Energi baru terbarukan merupakan energi alternatif yang potensial untuk menggantikan peran sentral dari energi fosil yang telah berlangsung sejak awal abad ke 20.

The paper discusses the design options for a concentrated solar power plant in Al-Khobar, Saudi Arabia. The specific conditions, in terms of weather and sun irradiance, are considered, including sand and dust, humidity, temperature and proximity to the sea. Different real-world experiences are then considered, to understand the best design to adapt to the specific conditions. Concentrated solar power solar tower with thermal energy storage such as Crescent Dunes, or concentrated solar power solar tower without thermal energy storage but boost by natural gas combustion such as Ivanpah are disregarded for the higher costs, the performances well below the design, and the extra difficulties for the specific location such as temperatures, humidity and sand/dust that suggest the use of an enclosed trough. Concentrated solar power parabolic trough without thermal energy storage such as Genesis or Mojave, of drastically reduced cost and much better performances, do not provide however the added value of thermal energy storage and dispatchability that can make interesting Concentrated solar power vs. alternatives such as wind and solar photovoltaic. Thus, the concentrated solar power parabolic trough with thermal energy storage of Solana, of intermediate costs and best performances, albeit slightly lower than the design values, is selected. This design will have to be modified to enclosed trough and adopt a Seawater, Once-trough condenser. Being the development peculiar, a small scale pilot plant is suggested before a full-scale development.

The urgency of the work is due to the feasibility of increasing the energy efficiency of solar power plants through the use of solar energy concentrators. Ways to improve the energy efficiency of solar panels using a sys-tem of directional mirrors, flat Fresnel lenses, spherical concentrators and trackers have been investigated. It is established that the most optimal way to improve the energy efficiency of solar panels is to use inexpensive track-ers with a simple design. The analysis of known types of solar panels, which differ in materials from which their elements are made, and the coefficients of efficiency – dependence of energy produced by a photocell on the intensity of solar radiation per unit of its surface has been carried out, and the type of solar panels by the criterion “price-quality” has been selected. A tracker design has been developed to track the angle of inclination of solar panels to increase efficiency. The electricity generated by the proposed solar power plant was calculated using an online calculator. It is projected to reduce losses when generating electricity for a given power plant due to the use of a tracker compared to a fixed power system, with the same number of solar panels. In order to reduce the cost of the tracker, it is suggested to orientate it to the south at once, and to change the inclination angles twice a year (in early April and late August). The energy efficiency of the power plant is calculated in two stages. At the first stage the amount of electricity from solar panels per year when adjusting only the angle of inclination of the panels to the south is calculated. At the second stage energy efficiency of the power plant is calculated taking into account the increase of energy efficiency of the solar power plant when using the tracker system. The calculated electricity generation of the proposed solar power plant with tracker confirmed the efficiency and feasibility of using the designed tracker system. The application of the designed tracker system allows to increase the energy efficiency of solar panels by an average of 25%.
