Electric vehicles (EVs) have been gaining popularity in recent years due to growing concerns about fuel depletion and increasing petrol prices. Random uncoordinated charging of multiple EVs at residential distribution feeders with moderate penetration levels is expected in the near future. This paper describes a high performance voltage controller for the EVs charging system, and proposes a scheme of asymmetric synchronous reference frame controller (ASRFC) in order to compensate for the voltage distortions and unbalance distribution system due to EVs charger. This paper explores the power factor of distribution and residential network under random EVs charger on the bus load. ASRFC and harmonic voltage compensator (HVC) are employed for static VAR compensator (SVC) in this paper. The proposed scheme can improve the power factor and total harmonic distortion (THD) of the smart grid due to the EVs charger in grid. The effectiveness of the scheme was investigated and verified through computer simulations of a 22.9-kV grid.

“…Due to the non-linear characteristics of these receivers (using diodes, thyristors or transistors to convert AC voltage in DC voltage and DC voltage in AC voltage or DC voltage in DC voltage), in industrial distribution systems harmonic currents occur. These, harmonic currents, leads to the distortion of the voltage curve at the point of common coupling (and in other parts of the distribution system), so are affected and other customers, non-harmonic polluting [1,2]. Resonance phenomena can increase the harmonic components of voltage that will lead to increase the voltage in different parts of the electricity supply system, overloading of transformers and, in particular capacitor [3].…”

“…Designing a harmonic filter has conventionally been by a trial and error approach. Various formulations for a more systematic approach to design harmonic filters have been developed in the decade [1][2][3][5][6][7]. Although effective in eliminating the harmonic, some of these methods did not consider the cost of filter elements.…”

“…In [7], the coordination controller is proposed by using ANN (Artificial Neural Network) as a classifier for tap position, but it needs a lot of data for training the ANN and is applied to a specific case. In [8,9], the coordinated control system between the SVC and ULTC of the distribution substation is proposed. The objective of the coordinated control of [8,9] is to minimize the number of unnecessary tap operations and to provide a better voltage profile.…”

-This paper proposes a new coordinated voltage control scheme between STATCOM (Static Synchronous Compensator) and reactive power compensation devices, such as shunt elements(shunt capacitor and shunt reactor) and ULTC(Under-Load Tap Changer) transformer in a local substation. If STATCOM and reactive power compensators are cooperatively used with well designed control algorithm, the target of the voltage control can be achieved in a suddenly changed power system. Also, keeping reactive power reserve in a STATCOM during steady-state operation is always needed to provide reactive power requirements during emergencies. This paper describes the coordinative voltage control method to keep or control the voltage of power system in an allowable range of steady-state and securing method of momentary reactive power reserve using PSS/E with Python. In the proposed method of this paper, the voltage reference of STATCOM is adjusted to keep the voltage of the most sensitive bus to the change of loads and other reactive power compensators also are settled to supply the reactive power shortage in out range of STATCOM to cope with the change of loads. As the result of simulation, it is possible to keep the load bus voltage in limited range and secure the momentary reactive power reserve in spite of broad load range condition.
