Abstract

The need for new plants is needed to balance the demand for high electricity. To anticipate this, it is necessary to accelerate the achievement of the level of utilization of new and renewable energy (EBT) in the energy mix for electricity supply by encouraging the use of energy from water, biomass, solar, wind to electricity. The Biomass Power Plant (PLTBm) is one of the environmentally friendly alternative power plants that produce electricity and heat by burning biomass in boilers in this case from wood waste from furniture and old rubber trees. The Interconnection System will be implemented in this PLTBm, where interconnection with the existing 20 kV system will be carried out. Research carried out includes power flow, voltage drop, losses, and short circuit. By conducting this study, it can be seen the profile of the overall system operation before and after this interconnection. The simulation results show that the PLTBm connected to the nearest feeder point from the generator is the best choice in terms of making the system voltage better between 19.1 kV and 20.17 kV. Power losses range from 439 kW and 5005.4 Kvar as well as short circuit currents, namely 13.73 KA.

Highlights

  • Electrical energy has become one of the needs in the modern era today

  • The authors in this study made a simulation of a Biomass Power Plant (PLTBm) with a capacity of 1 x 9.9 MW which was interconnected with a 20 kV network

  • The interconnection system is an electric power system consisting of several electricity centers and several substations (GIs) that are interconnected with one another through a transmission line and serving the load at the connected substation

Summary

Introduction

Electrical energy has become one of the needs in the modern era today. Demand for electricity has increased along with technological developments, growth in population, business and industry. The authors in this study made a simulation of a Biomass Power Plant (PLTBm) with a capacity of 1 x 9.9 MW which was interconnected with a 20 kV network. The biomass comes from wood waste from the furniture industry, and old rubber trees [2] This interconnection system study certainly needs to know the best connection point option in PLTBm, make a connection design and determine the type of PLTBm delivery to a 20 kV system, and find out changes in voltage profile, short circuit current and power losses after connecting to a 20 kV network [2] Besides that, load growth projections are carried out for several years, so the load points can be estimated in the number of each grid according to its geographical structure. Research can be a reference for the developer in interconnecting the Biomass Power Plant to a 20 kV system
