Аннотация

The article studies the possibility of improving the most efficient integration of solar power plants (SPP) with the electric grid by analyzing foreign scientific literature. The reasons for the inefficient integration of SPP and the power system are identified based on the results of scientific theoretical and experimental works by leading experts from developed countries. The issues of variability of weather conditions, the influence of external and internal factors on the operation of the network, the use of the most advanced technologies for managing the network, the method of accumulating the generated energy by batteries and their impact on the distortion of the energy parameters of the network are considered. The issues of introducing the technology of modern converters, anti-islanding, protection, forecasting the "sun-grid" system and smart grid are described. The methods of various scientists used in the integration of solar photovoltaic plants to electric grids and their results are discussed. Attention is paid to the development of control algorithms, the creation of simulation schemes of models. The main directions of methods for efficient connection of SPP to electric grids are indicated. Possible cases of failure of power plants, power lines and the safety of the entire system are taken into account. The technical and economic aspects of the problem of the issue under consideration in the construction of integrated systems in hard-to-reach areas of the planet are considered. It is recommended, as an important step, to optimize the implementation of Internet of Things (IoT) technology, smart monitoring of the generation of electrical power received from solar power plants, accumulation and consumption of energy by consumers. Keywords: Solar power plant, electric grid, integration, efficiency, control, protection, security, continuity, advanced technology, algorithm. costs compared to some alternative energy sources Introduction: It is clear that over the last twenty years, and minimal operating conditions. from the point of view of climate change and energy security, significant work has been done in the field of In recent years, the integration of solar power plants integration of alternative sources of electrical energy into the power grids of the energy system has started with the electricity supply system. The result of this is to develop. Such a possibility allows to maximize the an increased interest not only by the public authorities use of converted energy by consumers of different of energy facilities, but also by the population of types such as technological installations of industry and countries. Among non-conventional sources of electric population. According to the opinion and conclusions energy, the generation of the latter and reducing the of international observers, as a result of the consumption of gas fuel in greenhouses, the most development of industry and the increase in the realized by the use of solar energy. Photovoltaic amount of energy exchange, the amount of CO2 gas systems (PV) in this sense are efficient and quite emitted into the atmosphere is increasing[1÷3]. This durable. In addition, they already require relatively low can be clearly seen in Figure 1.

Amount of CO2 gas spreading into the atmosphere [1]. systems, due to the negative effect on the network There are some recommendations to address this frequency and voltage, the stability of the power problem. The first of them is [2], in order to solve this network is disturbed. Therefore, considering the problem, the creation within regional, national, or even continuous increase in the number of solar panels, the global levels of the energy system, linked by larger reliable management of the integrated solar power interconnected systems, for the sharing of resources. system and its efficient utilization with the power grid In this direction, extensive work has been done by the require new management strategies. Global Energy Interconnection Development and Cooperation Organization (GEIDCO). The second of The ability to generate electricity from photovoltaic them is aimed at the creation of self-managed systems is considered to be the most basic property. sustainable networks for large energy systems, These properties, depending on a variety of indicators, development of regional solutions and smart energy vary from application to application and technology. systems. The efficiency is only increased by precise calculation at the time of installation. However, despite the rather Due to the emerging conditions of local power high accuracy of accounting for all the influencing producers, many changes in technology and business factors on the operational properties of SES, there are are taking place. In particular, this is the case for a number of problems that arise during
