Abstract

In this article, the authors consider the materials of research on the construction and operation of intelligent power supply systems with a nominal voltage of up to 1000 V, containing distributed generation facilities. The author’s approach to the construction of microgrids based on multi-contact switching systems is proposed. The similarities and differences of the presented concepts are determined. The main problematic issues that arise in the process of implementing projects for the construction of microgrids and the management of electric power modes of operation are formulated. The ways of solving the problems related to the management of the modes of operation of microgrids are proposed.

Highlights

One of the most promising areas of modernization of grids of the lowest class of rated voltage up to 1000 V is the construction of intelligent active-adaptive electrical networks-microgrids
This circumstance is caused by a number of reasons, such as the lack of the necessary amount of regulatory legal acts, regulatory and technical documents [3], the relatively small prevalence of generating sources based on renewable energy [4] and electric energy storage devices in power systems [5]
The key idea of the project is to build rural electric grids based on the widespread use of the devices of the new generation of intelligent distribution power routers (IDPR) [8]

Summary

Introduction

One of the most promising areas of modernization of grids of the lowest class of rated voltage up to 1000 V is the construction of intelligent active-adaptive electrical networks-microgrids. The idea of creating microgrids was formulated in the first half of the 2000s [2], the stage of implementation and construction of microgrids does not go beyond the scope of the diploma and research papers. This circumstance is caused by a number of reasons, such as the lack of the necessary amount of regulatory legal acts, regulatory and technical documents [3], the relatively small prevalence of generating sources based on renewable energy [4] and electric energy storage devices in power systems [5].
