Pilot centralized solar power station in remote village, Rompin, Pahang

Abstract

Ab.f/racl-·Malaysia has considerahle number of widely deployed small rural areas. These hamlets are ver y much associated with the aborigines' or better known as 'Orang Asli' residents. Normally they get their source of energy from candle or kerosene light while some richer communities can afford generator sets.Conservatively, solar photovoltale systems are installed as standalone system to provide basic electricity to each aborigines home. On the other hand, for this project, a pilot centralized solar power station was Installed to provide electricity to fifteen houses at a small village east of Malaysia.This system Is the first solar photovoltalc system Installed at the 'Orang Asll' village In Mlllllyslll.This system will be the first ever built for the orang IIsli settlement at Pllhang.The objectives of this project lire to design and install the solar power stllUon lit remote location and to develop standard design of stand·alone solar power stillion sultllble for Maillysia.Orang Asli residents at Kampung Denai was chosen because there Is a school for the Orang AslI children. Moreover, the remote communities lire living in strlltil1clltion, which makes electrical wiring easier. Furthermore, the remote area Is far from the rast Irllnsmlulon line And cumbersome to bring diesel through the rough and unpredictable land road.The milin domestic energy 11 for residential purposes (e.g.small lighting unit, radio, television, video, etc.). The load demand WIIS (1I1(ulated bllsed on the previous diesel generator set. The generator capuJty is IS.6kW. The solar sizing WIIS done both for the home and school IIppilances lit Kllmpung Dena!. The maximum demand measured was 4195.35 kW.The pilot centralized solar power station consists of 10 kW photovoltaic panels, 10 kW Inverter, 150 kWh battery and other baillnee of system. A generlltor set with capacity of 12.SkVA is Installed for back up and during monsoon seuon. This paper will present status of the system, operational and maintenance issues, load profile of the solar power station and economics and system deSign of the whole s y stem. Keywords-solar photovoltaic, 'orang IISI1' and solar hybrid power station I. INTRODUCTION T NB has been involved with solar since the 1980s. At that time, most solar projects undertaken by TNB in Peninsular Malaysia were associated with decentralized stand-alone system for the Rural Electrification Program. As it is very expensive to provide electricity supply from the grid to the rural area, stand-alone solar PV systems were recognized as a cost-effective option to electrify the remote villages Building this solar power station will contribute to fulfill the Eight Malaysian Plan that is to supply about 5% of the electrical energy through the application of the 0-7803-8208-0103/$17.00 ©2003 IEEE. renewable sources of energy. In crises where such comillunities me widely scattered. having small loads and remote and far away rrom the unified grid, solar energy can play an important role tn their socio-economic development.

Hybrid power systems – Sizes, efficiencies, and economics

“…Ismail et al. (2003) designed and installed a stand-alone PV-DSL-BAT HPS (PV = 10.0 kW, DSL = 12.5 kVA, and BAT = 150.0 kWh) for the residents of at Kampung Denai village in Malaysia.…”

Effects of DC line voltage environment on different types of compact fluorescent lamps operation

“…This is worth to look into as most of the rural solar electrical power system are producing 24Vdc as initial output power with lighting load is 100% are using CFL and most of the other load are also DC compatible [7][8][9][10][11] thus the complex DC/AC inverter could be fully optimized if the DC/DC converter could be introduced parallel into the system.…”
