Abstract
This paper presents the analysis of a Voltage Source Converter based HVDC (VSC-HVDC) system applied for evacuation of power from a medium size Independent Power Producer (IPP) with a contractual requirement that a minimum quantum of the installed capacity is to be transmitted to the permission granting agency’s grid substation. The balance power could be sold by the IPP to any other customer through open access power transmission. In the system considered, at sending end, AC power is supplied from the IPP to a DC line and also to an AC line. The DC line transmits pre-defined amount of power (equal to 60% of net power available after auxiliary consumption) to the agency’s grid substation and the AC line facilitates transmission under open access. The AC line is connected to the central grid’s substation. At the receiving end, the agency’s grid substation is interconnected to the central grid substation through another AC line. For such a transmission system requirement, a high degree of control is necessary and VSC-HVDC technology emerges as a suitable option. In this paper, a detailed simulation of power flow controllability using a novel active power controller under different generation levels of IPP is carried out and the results are presented.
