Abstract

Power systems in all over the world have increased in size and complexity due to rapid growth of widespread interconnection. This situation will make power system operated closer to steady-state stability limit (SSSL) resulting in higher probability voltage instability or voltage collapse. This paper presents SSSL assessment in power system using Artificial Neural Network (ANN) model based on REI-Dimo method. The equivalent REI-Dimo is used to determine SSSL index of the power systems. Then, the result of REI-Dimo will be taught on ANN method via online. Studies were carried out on a Java-Bali 500kV system. The simulation showed that the proposed method could accurately predict the proximity to SSSL in power system. The method was computationally efficient and suitable for online monitoring of steady-state stability condition in the power systems.

Abstract

Load scheduling is essential for optimizing power transmission on the system. The way to produce a stable electrical energy transmission system is to minimize transmission losses using between the moment of inertia and power on the generator. The generation noise is a description of the power losses on the transmission line generated when the power plant sends the load power. Transferring power from a high losses plant to a low losses plant. Rescheduling System can minimize transmission system losses. In this research, the scheduling result of this method is compared with the realization of scheduling of thermal generators from PT PLN (Persero) Sulselbar Central Disbursement and Control Center (P3B). This comparison aims to prove this method better than scheduling realized PLN, so that found also advantages and disadvantages method. After the research, this method produces a generation power that is close to stability, because the amount of power generated close to the power generation of PLN in fulfilling the same load demand remains with smaller transmission losses and cheaper fuel costs. The result of stable loading results in the efficiency of the electricity company so that it can reduce the operational cost of the generation and of course indirectly impact on the low cost of electricity production.

Abstract

The availability of hot water energy sources in Pincara Village, North Luwu Regency, South Sulawesi Province, is a potential that must be developed as a source of electrical energy for the people in the village and surrounding villages. The existence of cheap energy sources will have an impact on improving the economy for villagers, most of whom make a living as farmers. In line with the development of industrial development in developing countries such as Indonesia where electrical energy is needed in increasing amounts of capacity, conventional sources of power generation (oil/gas) will not meet the required supply. Geothermal is an alternative to renewable energy sources other than biomass, hydro/wind/solar power, sea waves and nuclear power; which may be the main choice as a substitute for conventional/non-renewable energy sources. In connection with the direct use of geothermal energy sources that have low temperatures which are considered uneconomical, from these conditions, a technology is needed that is able to utilize geothermal energy sources that have low temperatures. One of the technological innovations for utilizing geothermal energy that has a low temperature is Organic Rankine Cycles. Organic Rankine Cycle (ORC) which is a modification of the Rankine cycle by using refrigerant as a working fluid to produce electrical energy. This system consists of four main components, namely the evaporator, turbine, condenser, and pump. The working fluid is pumped into the evaporator to generate steam.
