Solar Power Plants

Solar power plants are power plants that convert solar energy (light) into electrical energy. Generation of electricity can be done by using photovoltaic or can also called solar cell, which happened at this time, solar cell can not absorb sunlight optimally, because solar cell only silent in one direction (static) therefore needed smart system for generator Solar power for solar power plants to work more optimally, to make the smart system is needed to read data from several sensors. To find the direction of the arrival of the sunlight rays, used four light dependent resistor sensor (LDR). Light intensity data processing, motor rotation direction determination and other sensor data will be done by microcontroller. Then the data residing on the solar power plant will be displayed on the display and measured how much different in voltage, current and power generated by solar panel. Then the output of the solar power plant be compared among the system with tracking and without tracking. Keywords: PLTS, Light Sensor, voltage, current and power

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.

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.

Introduction. An urgent scientific problem is to increase the efficiency of using solar energy in solar power plants (SES). The purpose of the article is to study methods for increasing the efficiency of solar power plants. Materials and Methods. Solar power plants based on modules with a two-sided working surface are considered. Most modern solar power plants use solar modules. The reflection of solar radiation from the earth’s surface provides an increase in the production of electrical energy by 20% compared with modules with a working surface on one side. It is possible to increase the efficiency of using solar energy by increasing the annual production of electric energy through the creation of equal conditions for the use of solar energy by the front and back surfaces of bilateral solar modules. Results. The article presents a solar power plant on a horizontal surface with a vertical arrangement of bilateral solar modules, a solar power station with a deviation of bilateral solar modules from a vertical position, and a solar power plant on the southern slope of the hill with an angle β of the slope to the horizon. The formulas for calculating the sizes of the solar energy reflectors in the meridian direction, the width of the solar energy reflectors, and the angle of inclination of the solar modules to the horizontal surface are given. The results of computer simulation of the parameters of a solar power plant operating in the vicinity of Luxor (Egypt) are presented. Discussion and Conclusion. It is shown that the power generation within the power range of 1 kW takes a peak value for vertically oriented two-sided solar modules with horizontal reflectors of sunlight at the installed capacity utilization factor of 0.45. At the same time, when the solar radiation becomes parallel to the plane of vertical solar modules, there is a decrease in the output of electricity. The proposed design allows equalizing and increasing the output of electricity during the maximum period of solar radiation. Vertically oriented modules are reliable and easy to use while saving space between modules.

Indonesia is a country that is geographically located right in the equator and variously advantage and the wide for the use of solar energy. Indonesia has a relatively high radiation level, which is 4.80 kWh / m2 / day. Cemara Island is a tourist place but does not have electricity from PLN because access to its location is still difficult to reach. So from that chosen the planning system for the use of electrical energy using solar energy. However, economic analysis is needed so that the estimated weaknesses of the off-grid solar system can be estimated so as to reduce the risk of losses. The testing of each component in the Solar Power Plant system also needs to be done to determine the condition and quality of the components to be used. The economic analysis of the Cemara Island Solar Power Plant System with an initial investment of Rp 52,553,000, in scenario 1 uses interest at 6%, then in scenario 2 without using interest. Through calculations by looking for the value of COE (Energy Cost), NPC (Net Present Cost) and BEP (Break-Even Point), so that costs can be calculated by the manager with the number of 11 managers per month.
