Summary: | Stability in grid network is important since it will have impact on the sustainability and reliability in delivering power and also limiting the total power losses. It also been used to define system ability turn back to steady state condition when a disturbance occurs within minimum time. Nowadays renewable energy is a main discussion for future energy source. Photovoltaic (PV) is one of common discussion and it is a part of grid connected generation. PV generation is depending on the cloud clearness and the generation will varies accordingly. When it connected to the grid, it has significantly impact on the power system in terms of voltage fluctuation, power quality and power control. For this simulation brief study on the voltage profile in the steady stage and also transient stability using IEEE 9 bus as a test system. Study on the stability of the system when of PV penetration in steady state and fault applied has been presented. Simulation study cases are Case 1: Generator as only source for the test system in steady state and fault condition applied to one of the system bus. Case 2: PV as sole source for the test system except for slack bus in steady state. Case 3: PV and Generator as source except for slack bus with different PV penetration in fault condition applied to one of the system bus. The study of stability in this system has been carried out in short terms disturbance. Rotor angle at generator and the variations of voltage at buses been observed for the maximum PV penetration until the slack bus act as motor instead of reference. |
