Abstract

This article presents an efficient method for prosumer connection to the distribution line. The prosumers can be connected to the distribution line using specially designed controllable reactive impedance. The reactive impedance is controlled using specially designed coils and magnetic core. The internal coil is wound in the toroidal direction (across the z-axis) and creates a toroidal shape. A thin ferromagnetic strip is coiled on this toroidal shape in the poloidal direction to form the ferromagnetic core. Then, an external coil is wound on this ferromagnetic core in the poloidal direction. The internal coil is controlled by the inductive impedance of the external coil, which is related to the anisotropic properties of ferromagnetic strips. The internal coil is connected between the power supply line and a prosumer. This arrangement confirms the magnetic independence of coils and the symmetry of the current in the internal coil. The magnetic coupling between both coils is very low (~0.015–0.017) and appropriate for engineering applications. It is approved that the impedance of the internal coil is changed due to the anisotropic magnetic properties of the core material.

Highlights

In the present day, the consumers look to additional energy generation facilities to fulfill their increasing energy demands [1,2,3,4,5,6]
It is important to point out that the external coil remains open during circuit the internal coil measurement and vice and versa
It is observed that the impedance of both coils decreases during the internal coil measurement vice versa

Summary

Introduction

The consumers look to additional energy generation facilities (e.g., solar, wind) to fulfill their increasing energy demands [1,2,3,4,5,6]. Renewable energy produced by consumers can be utilized for themselves and can be transferred as surplus energy to the distribution grid. Such consumers are termed as prosumers [7]. Efficient and accurate analog control is required Such control should equalize the energy flow balance between prosumer needs and its generation ability by regulating power flows and prosumers in the distribution line [9].
