Abstract : Electric Spring (ES) offers voltage and power reliability in a grid powered by weakly regulated/standalone distributed energy sources. Electric vehicle connected to an intermittent renewable power supply needs reliable charging potential across the system for efficient charging. The prevailing distribution system must be made capable of handling the extra load caused by the immense number of EVs. In a poorly regulated grid, the electric spring has been recommended as a demand-side management strategy to regulate voltage and power. Using electric spring, this paper proposes to support the voltage level of a typical distribution network with a high electric vehicle penetration. In addition to voltage support, the proposed electric spring embedded with non-critical loads will act like a smart load capable of demand-side management with reactive and harmonic compensation. The Electric spring will ensure continuous supply across the critical loads in case of any intermittency occurring while using green power. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
