<span lang="EN-US">Decarbonizing power generation and reducing greenhouse gas emissions require renewable energy sources. Intermittent nature of renewable energy sources can cause blackouts, fluctuation in voltage, grid-connected inverter usage, inability to predict power generation, fluctuations in voltage and frequency. It is possible to balance between the supply and demand of power to overcome these problems by using an electric spring (ES). It is necessary to study its work, types, and controlling actions for realizing the benefits of the electric spring. This paper reviews the hardware structure of an ES based on voltage-source inverter (VSI) and current-source inverter (CSI) topologies, in single-phase and three-phase AC power distribution systems with renewable energy sources. The structure, control strategies, operating modes, advantages and disadvantages of each ES topology are elaborated to make it a suitable alternative for resolving different power quality issues caused due to the high penetration of renewable energy sources.</span>

“…Reference [87] uses an improved phase-locked loop (PLL) together with independent δ control in each phase to reduce unbalance and harmonic distortion in addition to stabilizing the mains voltage of the microgrid This is achieved by an improved PLL that separates the fundamental component of the positive sequence of the microgrid voltages from the other sequences and harmonics. An ES based on neutral point clamped H bridge inverter is shown to produce superior high-frequency harmonic suppression and improved total harmonic distortion in [88].…”

Increasing use of renewable energy sources to combat climate change comes with the challenge of power imbalance and instability issues in emerging power grids. To mitigate power fluctuation arising from the intermittent nature of renewables, electric spring has been proposed as a fast demandside management technology. Since its original conceptualization in 2011, many versions and variants of electric springs have emerged and industrial evaluations have begun. This paper provides an update of existing electric spring topologies, their associated control methodologies, and studies from the device level to the power system level. Future trends of electric springs in large-scale infrastructures are also addressed.

“…2 c ) is more elaborate as compared to the half‐bridge and full‐bridge because it uses an advanced PWM technique. Also, the output voltage has a lower harmonic content [29]. It can be seen that the three single‐phase versions of the ES‐1 use an inductive–capacitive LPF which allows the connection in series with the PCC and the non‐critical load.…”
