Abstract:
Battery Charging Station (BCS) is needed by Electrical Vehicle (EV) to refill electrical energy. BCS obtains electricity supply from the electric power system. However, the existence of BCS can cause the bus voltage to become unstable. This paper discusses how to maintain the stability of the bus voltage by interconnecting the wind power plant (WPP). The method is use four types of WPP. WPP first type is Fixed-speed conventional induction generators (FSCIG). WPP second type is Variable slip induction generators (VSIG). WPP third type is Variable doubly fed induction generators with rotor-side converters (DFIG). WPP fourth type is Variable speed with full induction generators (FCIIG) interface converter. In addition to using the four types of WPP, it also uses a combination of WPP first type with third type, second type with fourth type, and a combination of all types of WPP. Voltage analysis uses the P-V curve to show the sensitivity of active power changes to bus voltage change. Q-V curve to show the sensitivity of reactive power changes to bus voltage change. This paper focuses on stable margin areas on the P-V and Q-V curves. Based on the results of all the interconnection conditions of the types of WPP and BCS, the reference is at the widest margin of the stable voltage area. FCIIG and BCS interconnections on bus number 14 are capable of producing the widest stable margin area. The highest active power operating range is from 1.15 MW to 1.95 MW. As for the operating range of reactive power from 0.671 MVAR to 1.22 MVAR. Operation of the two power ranges keeps the voltage in a stable area.
