Power System Optimization and Stability

The article provides an overview of regulatory legal acts, incentive mechanisms, the share of implementation of distributed generation systems, considers the features of a centralized and decentralized power supply system in terms of changing operating conditions. The possibilities of using systems with distributed generation sources are considered. Ways of integrating distributed generation systems that form several local sources of electrical energy with a centralized source. As an example, the power supply system of industrial enterprises of the Konibodom district of the Sughd region is considered. The existing single-line diagram of power supply of industrial enterprises is presented. The perspective loads of industrial enterprises are analyzed. The perspective consumed active, reactive and full power of enterprises, power factor taking into account the length of the distribution network are given. The calculated currents are determined in all branches of the circuit with a centralized power supply. Taking into account the power consumption and geographical location, a design diagram was drawn up with three power sources. When calculating the electrical circuit, the method of two nodes was applied. The total, active, reactance of the circuit with three power supplies has been determined. The currents in individual branches of the power supply system of industrial enterprises are determined.
