Abstract

The integration of Renewable Energy Plants, especially Hydrogen, is one of the considerations in supporting net zero emissions in 2025 by 23% following the renewable energy mix plan at RUPTL. To determine the network impact due to the integration of the Green Hydrogen Plant (GHP) with transient study scenarios, system reliability, and reserve margin. The method for determining the capacity of the Green Hydrogen Plant (GHP) is by looking at the Renewable energy quota allocated in the isolated grid area. From the results of the study obtained in this transient simulation, the system frequency value is still within safe limits in the grid code, where the results of the swing frequency value are at least 98.5%. For Power Angle stability, the lowest swing result of -700degree is obtained within 5 seconds. So the reactive power requirement is 0.75 MVar of the system in the swing requirement of the trip condition. The reliability index obtained by the system, when interconnecting with the Green Hydrogen Plant (GHP) has a better reliability level value. This can be seen from the index of disturbances saifi, saidi, caidi is getting lower. The system reliability index is still within safe limits following SPLN 68-2: 1986. In addition, the interconnection system with the Green Hydrogen Plant (GHP) has the highest reserve margin of 3.25 kW at 09:00, when the Green Hydrogen Plant starts production capacity of 5 MW.

Abstract

Penetration of hosting capacity in radial type power distribution systems aims to increase the voltage profile on the end customer side. The more electricity customers increase, the more electricity user load growth will increase. This results in a voltage drop on the end customer side in the radial distribution system, characterized by a voltage exceeding the minimum standard operating acceptable voltage. This paper aims to provide solutions to cases in radial grid type power systems in solve voltage drops. The addition of hosting capacity for distributed renewable energy generators is one of the goals to increase the capacity of the electricity system. This research uses the Ant Lion Optimization algorithm method to try to find the optimal location and capacity of Distributed Generation in the electric power distribution system. Penetration hosting capacity injects renewable energy generation in the form of solar cells. The simulation results show that the increased voltage profile in the electric power distribution system exceeds the minimum voltage drop standard. So that in reducing power losses in the radial type network.
