Jaringan power listrik kapal untuk kegiatan operasional pelayaran memiliki karakteristik 3 phase 450 VAC 60 Hz, sumber diproduksi generator dengan kapasitas 562 KVA. Gangguan pada jaringan adalah undervoltage dan overvoltage, kondisi ini menyebabkan terjadinya voltage collapse atau blackout. Voltage tidak boleh terjadi sistem power, karena itu banyak penelitian terdahulu membahas berusaha menga...

At present, it is very common to find renewable energy resources, especially wind power, connected to distribution systems. The impact of this wind power on voltage distribution levels has been addressed in the literature. The majority of this works deals with the determination of the maximum active and reactive power that is possible to be connected on a system load bus, until the voltage at t...

The increasing energy demands are stressing the generation and transmission capabilities of the power system. Distributed generation (DG), which generally located in distribution systems, has the ability to meet some of the growing energy demands. However, unplanned application of individual distributed generators might cause other technical problems. The Microgrid concept has the potential to ...

This paper describes sensitivity indicator method to identify weakest bus of the system. It also describes method of calculating the amount of reactive power to be injected at the load bus to avert the voltage instability as the load on the load bus increases. In this paper IEEE-57 BUS system has been considered. First, the weakest bus is identified using sensitivity indicator method. Then Load...

This paper proposes a pricing system for power system security in deregulated electricity market that includes voltage stability constraint in a multi-objective OPF problem. The OPF maximizes social benefit, as well as the distance from the voltage-collapse point. While pricing system security, ancillary service such as reactive power has been included. Effect of N–1 contingency on pricing is a...
