Abstract

Electric Spring (ES) is a promising demand-side management technology to address power, voltage, and frequency fluctuations in power systems. Recently, ES has been applied to medium-voltage (MV) distribution networks based on a multilevel converter (MLC) and dual active bridges, but the designs have been limited to a single output port without the ability to distinguish between critical and non-critical loads. This paper proposes a new topology that utilizes an LLC converter that is dedicated to feeding non-critical loads. Additionally, a power balancing control method is proposed to achieve capacitor balancing in the MLC, enabling simple modulation techniques at the MLC stage. The results are validated through a microgrid MATLAB simulation.
