“…Reference [9] proposes a DC ES that uses the concept of an ES to a DC microgrid. References [10,11] investigated a G-ES topology where critical loads are connected to the critical section feeder to obtain high-quality power and no more separate smart loads are configured. The G-ES reduces the redundancy (excessive smart load devices) generated by the ES facing clustered critical loads.…”

SummaryThe advantage of a generalized electric spring (G‐ES) is that it solves the redundancy problem of a conventional electric spring (ES) in the face of critical load clusters. This paper first introduces Hamilton's principle into the G‐ES, derives the mathematical model of the G‐ES, and further introduces the topology of the G‐ES. Next, the working modes and working states of the G‐ES are defined. The working modes are used to reflect the combination of ES power inside the G‐ES, and the power conditions in specific working modes are described using a phase diagram. Then, the paper analyses the power case of the G‐ES to the external system, giving the respective working states according to their internal working modes. Finally, this paper introduces PQ control to the control strategy of the G‐ES and achieves control of the G‐ES working mode and its working state. The results of the study show that there are 100 working modes of the G‐ES, and 76 working modes have a specific working state. The correctness of the working mode and working state analysis is verified with the help of the MATLAB/Simulink simulation and experiment.

The emerging smart grid technology known as Electric Spring (ES) has been employed previously to maintain voltage and power stability in renewable energy-based grids that are minimally regulated or self-contained. This study thoroughly investigated the foundational theories, modeling approaches, practical uses, and restrictions associated with Electric Springs by analyzing existing Scholarly works in this domain Electric Springs implement a direct power control approach. solution for the next-generation single-phase Systems, addressing the limitations of current ES control methods. This solution aims to improve power management in microgrids, where integrating renewable energy sources (RESs) poses challenges due to the unpredictable power output. The challenge involves managing two aspects: the variable Power consumed by ES and the power fed into the grid. The suggested straightforward and accurate signal manipulation method, namely, ANN-based Electric Spring (ES), is set to be deployed. This technique can adeptly manage these aspects in both stable conditions and during transitions in Renewable Energy Sources (RES).
