Abstract

Installation of PV capacity that exceeds the demand of the distribution system can produce large currents that exceed the thermal rating of the electrical components and can cause export power to high voltage levels. Therefore, the purpose of this study is to obtain the PV hosting capacity of the Adinegoro feeder and to determine the voltage profile and power loss after installation of the PV. The research method is using power flow simulation with ETAP 12.6. The PV hosting capacity calculations of the Adinegoro feeder are carried out in six locations, i.e. five locations on the secondary network and one location on the primary network. The PV capacities are continuously increased until the receiving power from the grid reaches zero or no export power from the lower voltage level to higher voltage level. From the simulation results, it is obtained that the PV hosting capacity on secondary networks, is equal to 100% of the local load. While for the primary network, the maximum PV hosting capacity is 4400 kW. The installation of PV to the Adinegoro feeder can increase the voltage profile and reduce power losses in the system.

Abstract

The electric power distribution system will change very quickly along with the growth of the load which tends to increase every year. The increase of electricity demand must be anticipated with the addition of the number of generating plants that will integrate to the system in order to carry out continuous and optimal system operations. Before adding new generators to the system, a feasibility study will be conducted to provide optimal results using simulation of power flow studies. The connection of the Bayang Nyalo Hydro Power (BNHP) to the medium voltage 20 kV electricity system of the PLN with several operating scenarios provide significant results. The most optimal results have been obtained with scenario 2-2, which the operating voltage changed from 0.80 pu to 0.95 pu and power losses decreased from 2.04 MW to 1.67 MW. This provides a recommendation that the operating scheme of scenario 2-2 should be applied when the Bayang Nyalo Power Plant connects the PLN 20 kV system because this scenario does not require additional new investment from PLN.

Abstract

Microgrids will become common in future electrical distribution networks. Numerous operating modes that occur in microgrids make the development of protection schemes and settings challenging. This paper aims to develop a simple protection scheme for the Microgrid IEC Benchmark without any expensive equipment such as communication apparatus. The scheme consists of directional and non-directional overcurrent relays with standard inverse characteristics. For the simulation tool, Digsilent powerfactory is employed. Four operating modes of the microgrid are applied to verify the relays’ coordination. The results show that the proposed scheme successfully protects the microgrid during short circuit faults with acceptable time margins.

Abstract

Vehicle-to-Grid (V2G) technology is an innovative concept designed to support frequency stability by enabling two-way energy exchange between electric vehicles (EVs) and the power grid, especially in systems with high penetration of renewable energy resources. This paper examines the battery electric vehicles’ demand nature also as an ancillary support resource to address intermittency of renewable energy sources and grid frequency support through V2G technology. The study highlights technological issues such as degradation rates of batteries, communication difficulties, and scaling problems alongside issues of regulation and market that encompass large-scale implementation of V2G. Tackling the effectiveness of V2G systems in frequency regulation The effectiveness of approaches like virtual inertia emulation, enhanced control algorithms, and decentralized frameworks are discussed as ways of enhancing V2G systems. These findings reaffirm that V2G has tremendous potential in the electric grid yet, it must be noted that solving these issues remains critical through transformational research and policy strategy. The conclusions help to better understand the prospects for improving V2G towards more accurate support for frequency stability in transition to sustainable energy systems.
