Abstract
Abstract Jawa Bali 500 kV power system grid comprises of two large areas which are connected by two double circuit transmission lines. However, under high power transfer from east to west area on October 19, 2012 resulted in Jawa Bali power system experienced voltage drop until 0.86 pu in west area. Very low voltage may lead to voltage stability phenomenon. This paper would analyze maximum power transfer capability without and with introducing shunt compensators. Static analysis using P-V Curve method is aimed to assess voltage stability phenomenon. P-V Curve corresponds with total active power transfer (P) of two transmission lines connecting west and east area compared to voltage system (V) behavior in west area. The study also includes investigation of power transfer capability limit enhancement with use of shunt compensator compare to initial condition. Various options of shunt compensators considered are MSCs, SVC, and STATCOM. Power Transfer Stability Index and Q-V Curve sensitivity were considered to acquire list ranking location of shunt compensator. Based on static voltage analyses result, use of shunt compensators was proven to increase power transfer limit.
