Компенсація реактивної потужності в розподільних електричних мережах з відновлюваними джерелами енергії

Abstract

Master's qualification work is devoted to the peculiarities of solving the problem of reactive power compensation in electrical distribution networks, employing renewable energy sources (RES). Analyzes the regulatory framework that regulates the payment for the flow of reactive power in the distribution of electrical networks, as well as the reactive power compensation. The question of optimization of reactive power flows in distribution networks (RES) was investigated. The methods for solving the problem of optimal reactive power compensation in electrical distribution networks were defined, and the algorithms have been developed. The possibility of using economic equivalent of reactive power to optimize the levels of compensation for consumers was confirmed by computational experiments. Under health and safety emergency analyzes are harmful and dangerous factors at 110/35/10 kV substation "Mykhailivka" and suggested measures to safeguard personnel. Modes of electrical networks with renewable energy sources were calculated using software "VTRATY". It developed at the Department of Electric Stations and Systems Vinnytsia National Technical University.
