IMPLEMENTATION OF ELECTRIC SPRING FOR ENHANCING VOLTAGE AND POWER STABILITY WITH POWER CORRECTION

Abstract

ES ‘Electric Spring’ which called as smart gird device which used to dispatch active and reactive power in
the system which is connected between the Gird and Load or demand and supply. It has been proposed as the demand
side management technique to provide voltage and power regulation. In this paper, a new scheme is presented for the
implementation of the electric spring, along with non-critical building loads like electric heaters, refrigerators and
central air conditioning system. This is the control system provide power factor correction, voltage support, and power
balance for the crucial loads for example like the building's security system, in addition to the existing characteristics of
an electric spring of voltage and power stability. The proposed control scheme is compared with the original ES control
scheme where only reactive power is injected. The updated control system opens with the new way for the use of the
electric spring to a greater extent by providing voltage and power stability and enhancing the power quality in the
renewable energy powered microgrids.
