“…2. FACTS devices such as STATCOM as well as DVR provide a compensation of single point at the level of transmission and must therefore be mounted with far higher ratings, where ES works at several locations such as an inherent part of the partial load, which is also at the level of distribution and therefore less costly due to lower ratings [34].…”

The Mechanical Springs act has developed into electric spring (ES). The efficient law developed by Hooke’s, has been upraised with the new scientific application which pays vital role in this modern society. The main function of this highly new grid technology provides distributed energy storage, voltage regulation, amplify the power quality and stability in a highly and reliable way. So the improvised control scheme has been assist to open new and different avenues to utilize the electric spring to greater extent. Electric Spring is new and innovative concept by which modern society is able to renew natural energy in easy way. Power match between the generation facet as well as the demand facet will be effectively relieved. This theory transforms many non- critical loads with smart loads in the latest century that have automatically following power generation. It is a novel control approach which is needed in the new future smart grid. The previous concept of output voltage control turns into new one that is input voltage control which is based on reactive power to emphasize this work. Because of the rise in the growth of smart grids, micro grids and RESs, it seems to be observed that ES has been growing in popularity for the past few years. It is a form of power system stability solution and it will be ultimate demand side management which is ready to provide stability solutions.

“…Refrigeration, lighting, and heating loads are generally classified as noncritical loads. Previous reported uses of ES include its usage for voltage regulation, harmonic mitigation, and demand side management [18][19][20][21][22][23][24]. In addition, the ES has also been used to reduce energy storage requirement [25] and threephase load imbalance [26,27].…”

Although electric vehicles (EVs) offer a viable mean of commuting, their widespread penetration can have adverse effects on the current electrical distribution networks due to voltage drop and overloading of distribution transformers. In this work, a novel control scheme is proposed and implemented to support the voltage profile of a typical distribution network loaded by EVs. Electric spring (ES), a real/reactive power compensator, is driven by the proposed controller to provide voltage support under dynamic loading conditions. In the proposed scheme, the ES reference voltage is continuously determined and then compared with its instantaneous output voltage in a closed-loop configuration. The proposed controller is tested under various loading conditions both through simulations and digital implementation in the hardware-in-the-loop configuration to evaluate its overall performance. Results show that ES equipped with the proposed controller can be successfully used to fix the problem of the voltage drop caused by the sudden and simultaneous charging of EVs.

“…Unlike the traditional circuit compensation device, the ES operates in a distributed manner on the load side, making the power consumption more reliable on the load side [4]. Compared with the static var compensator (SVC), the ES boasts small capacity and high reliability [5]. Different from the traditional measures to alleviate RES supply fluctuations (e.g.…”

As a novel voltage control device, electric spring (ES) can effectively suppress the voltage fluctuations across critical loads (CLs), and solve the various problems with electrical quality induced by the grid access of renewable energy resources (RES). However, the traditional controllers for the ES system can no longer meet the control requirements, as the environment is complicated by the growing number of load-side nonlinear loads and uncertain disturbances. To solve the problem, this paper proposes a control system based on finite control set-model predictive control (FCS-MPC), and applies it to the ES. Firstly, a load-side circuit prediction model was established and analyzed. Next, a control system was designed based on FCS-MPC. Finally, the proposed system was proved feasible and effective through MATLAB/Simulink simulation and dSPACE physical experiment. The results show that the proposed FCS-MPC system can directly control the ES, easily handle system constraints, achieve robust dynamic and static performance, eliminating the need for pulse width modulation (PWM).
