“…The ES voltage injected in each phase is set to remove unbalance while minimizing the active power exchanged with the battery storage. In [89], a 3-phase ES is considered for voltage regulation and reducing unbalance based on the theory of instantaneous power which is verified experimentally. Reference [38] uses a modified instantaneous symmetrical component algorithm and hysteresis current control to operate ES in active power filter mode to mitigate harmonics, improve the power factor while regulating the mains voltage.…”

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.

“…Getting the absolute value of (17) gives According to (13), it can be obtained that the amplitude of V ES has a positive correlation with the absolute value of ΔP. Therefore, combined with the conclusion above, the amplitude of V ES should have a positive correlation with the absolute value of DEM -DEM-REF .…”

In active distribution network, the random power output by wind/solar distributed generation may cause the stochastic fluctuation of demand side power, which will bring difficulties to power dispatching. In this paper, a method of restraining the demand side power fluctuation of active distribution network is proposed, in which a new power electronic device—electric spring—is applied by 0°/180° phase control strategy. Firstly, the basic principles of electric spring are introduced. Secondly, the reason for demand side power fluctuation of active distribution network is analyzed. After that, the 0°/180° phase control strategy of electric spring is proposed to restrain the demand side power fluctuation of active distribution network and the selection basis of noncritical loads is also obtained. The simulation results show that the method proposed in this paper is effective and the obtained selection basis of noncritical loads is reasonable.

“…The versions above are also termed as ES generations since they are the milestones in the ES technology development. In addition to them, many other versions have been described [7]- [9]. Besides ACES, in recent times another kind of ES -referred to as DCES-has been studied to stabilize the supply voltage of the CLs connected to a DC microgrid [10], [11].…”

A Parameter-Exempted, High-Performance Power Decoupling Control of Single-Phase Electric Springs

et al. 2020

View full text Add to dashboard Cite

Electric Spring (ES) is an emerging technology intended to stabilize the voltage across the critical load (CL) of an end-user in the presence of fluctuations of the grid power. The most advanced way of controlling the so-called second generation of ES relies on the handling of both active and reactive power. However, the strategies used to implement such a control suffer from either the need of an a-priori knowledge of circuit parameters or a slow response to the grid power fluctuations. In this paper, a control strategy is proposed that overcomes these inconveniences. It relies on two problem-solving solutions, namely the closed-loop control of the dq components of the current drawn by the end-user and a feedback of the ES output current into the ES command. The setup of the proposed power decoupling control has just the features of being no affected by the circuit parameters and exhibiting an enhanced dynamic behavior. The features are validated by both simulation and experimental results. INDEX TERMS Electric spring, microgrid, power control, renewable energy source.
