Three phase fault is one of a transient phenomenon that must be isolate immediately to prevent losing synchron of generator in power plant, so that the system remain stable. Critical clearing time is maximum time allowed to isolate the system fault so that the system remain stable. Super capacitor energy storage installation to the system is one way to improve CCT value. Super capacitor is one of energy storage that be able to supply and store large amounts of electricity power quickly. Super Capacitor can improve CCT value by muffle oscillation of 3 phase fault. With higher CCT value, then time operation of protection system can be longer. The result is the system remain stable after fault removed and it can be improve transient stability in power system. Within an optimal sizing of super capacitor capacities for the system, then the value of CCT that obtained is higher than protection time operation. So that in this final project will be carried out an optimal sizing of super capacitor for improving transient stability with critical trajectory based on losing synchronism method

Permanent Magnet Synchronous Machines (PMSM) have low torque in a number of specific PT. Pertamina RU V Balikpapan will be integrated with electricity sources with PT. PLN. Then there will be a change in the generator operating pattern on the system so it needs to be analyzed again. The protection system aims to isolate the interference quickly, selectively, and coordinatively so that damage to the system can be minimized and the continuity of electric power can be maintained properly. The important thing that must be considered for protection coordination, especially in overcurrent relays, is filling the TDS (Time Dial Setting) parameter. TDS regulates the relay operation time in securing a disturbance. Generally, the TDS value is determined using a manual calculation to obtain a minimum TDS value. However, to get the right TDS value in coordinating with other relays it still uses trial and error methods. In this final project, we will discuss how to calculate the time dial overcurrent relay inverse setting with the adaptive modified firefly algorithm method in the electrical system at PT. Pertamina RU V Balikpapan considers integration with PLN to obtain a minimum TDS value. The result of this final project is to obtain a minimum TDS value in some cases typical types such as the longest channel, consideration of LVCB operating time, and short channels so that it can be well-coordinated with the long lines installed on the same bus.

Research and development on the implementation of renewable energy is growing rapidly, especially about photovoltaic (PV) and energy storage. Water pumped energy storage (WPES) is an alternative storage media in a standalone solar power system because of its longer technical life than chemical storage types, such as batteries. To assess the feasibility of WPES implementation as an energy storage in the standalone solar power plant system, the process of sizing the system components needs to be carried out by considering technical and economic aspects. This research will discuss the sizing process of standalone solar power system using WPES with closed loop reservoir systems and its economic analysis. The sizing process is carried out by the method of power balance, energy balance, and volume balance while economic viability is seen from the capital cost, O&M cost, and revenue from electrical energy absorbed by the load. In this study, the daily load profile with energy demand of 79 kWh and peak load of 4.36 kW. The analysis shows the need of 56 kWp PV system, 3800 m³reservoir capacity with 20m head. The calculation shows the technical efficiency of the system is 28.2%. From the economic analysis, the sistem’s payback period is 24 years, assuming the reservoir technical age is 50 years with net present value of Rp 2,072,823,731.86 and return of investment 105%.
