Abstract: In this technical paper, IEEE 14 bus system is connected with a solar photovoltaic (SPV) system. This interconnection of SPV and IEEE 14 bus system is evaluated during a fault condition. In this paper, the synchronous generator is replaced by a SPV unit. Primarily, a SPV system of 40 MW capacity is connected at bus 2 in place of a 40 MVA synchronous generator. When fault occurs on any of the transmission lines of IEEE 14 bus system, then the system becomes unstable for a short period of time. IEEE 14 bus works on 60 Hz frequency. SPV has an ability to fluctuate output power which depends on input temperature and irradiation of solar. By varying temperature and solar irradiation of SPV, output power may oscillate, but to build constant output power, we assume SPV to be under a standard test condition (STC). During fault condition, output of SPV may disturb and this observational study is the main purpose of this paper. The IEEE 14 bus system has three synchronous condensers (to maintain power factor) and one slack bus. When SPV is coupled with IEEE 14 bus, then the quality of power is reduced due to a harmonic effect in a SPV system. To reduce the harmonic effect, a filter system is used.

Keywords: IEEE 14 bus system; SPV system; synchronous generator; bus 2; standard test condition; STC.
