Indeed the control system can use that reactive power and the result is shown in Fig. 17. Fig. 17 shows as the reactive power requested by the EV fast charge can be provided by the BESS.
Reactive power compensation priority control for a special load In this experimentation the priority to the reactive power has been given. As seen before, the BESS can compensate the active and reactive power on the EV fast charge. A high active power threshold has been chosen in this experimentation to avoid active power compensation.
In , the method of trajectory sensitivity is used to select the location of reactive power compensation. The above reactive power compensation methods ignore the impact on the stability of the system. This paper proposes the voltage stability margin index on the basis of optimized equivalence.
The reactive power compensation helps to increase available maximum load of any transmission line to the thermal limits under stability ranges without complex sizing requirements. This is obtained by using traditional reactive power compensations such as series or shunt capacitors, and variable compensators.
Appropriate reactive power compensation can not only improve the stability level, but also enhance the power transmission limit. This paper is supported by the Science and Technology Project (5216A5200003) of Hunan Electric Power Co., Ltd. The authors do not have a conflict of interest.
The reactive power compensation and voltage control is primarily performed by selecting shunt devices that are shown in the first line of the figure. The SVCs are capable to present more accurate and smoother control comparing to mechanically switched shunt compensators.
