Abstract
The concept of electric springs (ESs) has been proposed as a new solution for stabilizing power grid fed by intermittent renewable energy sources. With a battery or active power source (DC, on the inside), the ESs can provide both active and reactive power compensations. So far, three typical topologies of single-phase ESs have been reported. Unlike traditional devices where power generation follows the load demand, the ESs are associated with non-critical loads form the so-called smart loads that transfer the fluctuated power to the non-critical loads, adaptively, according to the intermittent nature of power generation. After reviewing the main control strategies of single-phase ESs, the paper analyzes their advantages and disadvantages as well as their suitable applications. Comparisons among different control strategies on a specific topology version are implemented. Finally, conclusions and possible future trends are pointed out.
Highlights
The existing way by which power system operates is that power generation depends on the needs of the users
With the increasing capacity of power generated from renewable energy sources (RESs), the total power generation is more and more difficult to predict due to the intermittent nature of RESs, which might result in a mismatch between the load demand and power generation [1,2,3]
Maximum power point tracking (MPPT) technology is commonly used in wind or solar power plants, and the tracked active power is consumed by the electrical load at domestic home, which can be classified into CLs and non-critical loads (NCLs)
Summary
The existing way by which power system operates is that power generation depends on the needs of the users. There is no energy storage device in the ES-1 [6] It stabilizes the local mains voltage and adjusts. It stabilizes the local mains voltage and adjusts the power of the NCL through a reactive power to balance the power supply and demand, which the power of the NCL through a reactive power to balance the power supply and demand, which means it can only provide pure reactive power support and cannot provide active power. Are interrelated and inherently controlled, and the degree of control freedom in the method is one Under this control strategy, the power angle of the SL is not controlled and varies, during the grid. An inability to adjust the power angle of the SL and can only stabilize the grid voltage
