Abstract

The compensating devices are controlled in the structure of the automatic control system in conjunction with the sensors included in a particular node of the power grid. But the overall state of the local power grid for the reactive power flow is not considered. It is proposed to generate control signals to correction devices by processing the information obtained by monitoring from remote sensors of voltage and current of the distribution grid. It is possible to use the matrix method of forming the control signals to correction devices to adjust the grid parameters. To improve the energy efficiency of correction devices in the monitoring structure, it is proposed to use static reactive power compensators (SVCs) based on magneto-valve elements. The proposed distribution grid monitoring structure with the transfer of information over a local area network from sensors to correction devices makes it possible to stabilize the required grid parameters among consumers and minimize the loss of electrical energy from reactive power flow.

Highlights

Leading scientific research centers associated with the design of power grids, are focused on the new Smart Grid concept [1]
One of the subsystems of the Smart Grid is a flexible alternating current transmission system (FACTS), containing sets of adaptable power components that serve for increasing grid transmission capacity and improving the high-performance of the power grid and consumer reliability improvement [2]
The FACTS is based on reactive power compensation devices and correction devices of various circuitry solutions, e.g. static reactive power compensators (SVCs), with the ability to quickly change the reactive power [3]

Summary

Introduction

Leading scientific research centers associated with the design of power grids, are focused on the new Smart Grid concept [1]. For a more correct effect on the grid to maintain the required voltage or power factor, the SVC must be connected to a specific grid design node, and must be controlled by a control signal that evaluates the state of the monitored grid. For this purpose, the SVC control system is included in the monitoring of the state of the grid, as a result of which an adjusted control action is generated on the SVC control unit making the effect on the grid parameters more optimal
