Voltage Profile Improvement of the 20 kV Painan Distribution System with Multiple Distributed Renewable Energy Generation

Abstract

This paper analyzes the effect of multiple Distributed Renewable Energy Generation penetration on improving the performance of the B3 feeder typical distribution system structure in Painan, Indonesia. Analysis uses a simple concept of load and distributed generation current injection at the distributed main, lateral and sublateral lines. The algorithm begins from completion of the main line variables, then uses an algorithm to complete the lateral line variables associated with the main line variable, and finally calls algorithms to resolve the sublateral variables associated with the lateral line variable. The results have shown that integrating three Distributed Renewable Energy Generation units to this distributed system has increased the minimum voltage of the main line from 17.35 kV to 20.37 kV, reduced active power loss from 1914.747 kW to 569.925 kW, and diminished reactive power loss from 650.747 kVAr to 188.624 kVAr.

Investigation of a 7-Level Inverter-based Electric Spring Subjected to Distribution Network Dynamics

“…Increasing Distributed Generation in Smart Grid systems impacts the reactive power flow in the feeder and thereby leads to voltage variations in the distribution system [1]. Also, constantly fluctuating consumer load demands effect the load of the distribution system.…”

Universal Switch for Measuring the Resistance of the Grounding Device Supports of the 110 kV Overhead Power Line

“…According to several authors (Abdurrakhman et al, 2020;Astahov and Belikov, 2013;Kolobov et al, 2016;Nazir et al, 2016;Nizhevskij and Nizhevskij, 2016) the devices to measure the resistance of the PD differ in their field of application, measurement ranges, circuits, noise immunity, and frequency of the measuring current, and the operation includes various measurement methods. If it is impossible or inexpedient to disconnect the lightning protection cable from the body of the support to measure the resistance of the protective device of the 110 kV OHL supports, you can use the pulse method developed at the Moscow Power Engineering Institute (MPEI) and the method developed at the Siberian Research Institute of Power Engineering (SibNIIE).…”

Solar photovoltaic systems in Indonesia's grid: experiences of end-users and evaluations of photovoltaic systems performance

“…The values for ηA,rated of the CIS and p-Si system were respectively 13.8% and 14.9%. The annual-averaged CF was 16.3% for CISS, 16.0% for CISC, and 14.1% for the p-Si system. to July 2018.…”

“…DG with renewable generation suits Indonesia's needs given its topography and the need for improving the reliability of the grid [16].…”

“…The other motivations for solar electrification in Indonesia include, among others, the increasing demand for electricity (around 5.5% annual growth) and economic growth of around 5% per year [70]. PV systems are suitable for use on the large islands (urban areas), particularly with respect to increasing the quality of the power supply [16] as Indonesia is characterized by the relatively low reliability of its electricity supply [215]. Meanwhile, on the smaller islands and in more remote areas, PV systems could play a significant role in providing electricity to local people who have not had it before, replacing fossil-fuel-generated electricity with renewables, and increasing the electrification ratio [150].…”
