Dc House: An Alternate Solution for Rural Electrification
International Journal of Trend in Scientific Research and Development, 2019
In today's date, India is a large consumer of fossil fuel such as coal, crude oil etc. The rapid increase in use of Non renewable energies such as fossil fuel, oil, natural gas has created problems of demand & supply. Because of which, the future of Non renewable energies is becoming uncertain. Now a day's electricity is most needed facility for the human being. All the conventional energy resources are depleting day by day. So we have to shift from conventional to non-conventional energy resources. In this the combination of two energy resources is takes place i.e. wind and solar energy. This process reviles the sustainable energy resources without damaging the nature. We can give uninterrupted power by using hybrid energy system. Basically this system involves the integration of two energy system that will give continuous power. Solar panels are used for converting solar energy and wind turbines are used for converting wind energy into electricity. This electrical power can utilize for various purpose. Generation of electricity will be takes place at affordable cost. This paper deals with the generation of electricity by using two sources combine which leads to generate electricity with affordable cost without damaging the nature balance.
Portable Energy Storage System for DC House and Emergency Response in Indinesia
Academic Society for Appropriate Technology, 2019
One of main problems in developing electricity grid for archipelago country like Indonesia is the geographical concerns as it consists of many islands. In some rural areas, electricity has not been available yet due to the limited infrastructure access, leading to high investment cost. In this study, a portable energy storage system based on the lithium-ion batteries called Tabung Listrik or TaLis (DC-based power bank) and DC house system were proposed as the solution for providing electricity for rural areas with relatively lower cost. TaLis is designed to be portable so it is easy to carry around as well as it can be used for many purposes. Since 2017, TaLis prototype has been used as the energy storage in a DC house system at Sekolah Master Indonesia, where an array of PV rooftop is functioned as the main DC power supply. Besides, some TaLis were also dispatched for emergency response during the disaster situations in Indonesia, such as during the measles outbreak in Asmat-Papua, the earthquake disaster in Lombok and tsunami in Palu.
Demonstration of multi-purpose battery charging station for rural electrification
Renewable Energy, 2003
Many rural market places in Bangladesh rely on inefficient and expensive fossil fuel based lighting. Photovoltaic (PV) based electricity is an interesting option to provide quality light and better service in these situations. A PV based micro-utility system was initiated in a rural market in Bangladesh in October 1999. Twenty one shop owners were provided electricity for 5 h a day on fee-for-service basis, and paid a tariff daily. A local operator cum technician was trained to take care of the system and in charge of repair, maintenance and tariff collection. Feedback from the users of the system indicates that PV based electricity has been providing very satisfactory service to the consumers. The success of this type of PV dissemination model has been due to the users' willingness to pay a daily tariff, clear agreements with the Bazaar Management Committee and users, and operator training. The model proved to be successful and two more rural markets showed interest in this approach of rural electrification. This is likely to succeed in other countries with similar socio-economic conditions.
The House Project: A Sustainable Alternative For Rural Electrification
Proceeding of International Conference on Science and Technology
In recent years there has been an outburst of interest in the use of renewable energy sources to reduce greenhouse gas emissions. These renewable energy sources are generally putting out dc power and hence some intermediate energy conversion to ac is essential for its use. Unfortunately, this much needed conversion yields not only extra cost to the system but also introduces power loss which consequently reduces system's efficiency. This DC House project aims to utilize the dc energy directly from renewable energy sources without the need for dc to ac conversion. Besides enhancing system's efficiency while reducing cost, the DC House's main use will be in locations where utility grid is out of reach or geographically inaccessible; hence, the opportunity to promote the use of renewable energy sources while providing electricity to those people who are less fortunate.

Most of the application of solar PV in Indonesia uses inverter, which is a complex and expensive electronics system. Many of the PV plants are in fault condition due to the failure of the inverter. This paper proposed DC wirings powered by solar PV for houses in the urban area of Indonesia. First, the paper reviewed the availability of electrical appliances powered by DC voltage supply. Secondly, it presents AC and DC house wiring designs for a house with 1 300 VA electrical power limit. Losses of both wirings are analyzed and compared, including the cost of wirings materials. The survey showed appliances such as air conditioning, fridgefreezer, television, washing machine, and other appliances are now available in DC voltage supply. A 48 V DC bus is chosen to minimize losses. From a cost perspective, AC and DC wiring systems are comparable, but the DC house is slightly more expensive due to the cost of appliances. The cost of DC wirings is lower due to the lower cost of the DC-DC c...

Providing accessible, affordable and renewable electricity to rural areas in developing countries like Indonesia, is arguably challenging. The higher initial cost of renewable, as compared to conventional energy technologies, is often viewed as an obstacle in the rural electrification decision-making process. This study is conducted to examine the techno-economic feasibility of renewable energy generation options to bring electricity to the rural villages in Indonesia with Belu Regency, East Nusa Tenggara (ENT) as a case study. In this study, three village electrification scenarios were generated: basic (with the demand load of 150,5 kWh/day), moderate (359,9 kWh/day) and advanced electrification (579 kWh/day). To supply the load, three energy technologies were compared: conventional technology (diesel-powered); renewables technology (solar PV, and wind turbines); and hybrid technology (combination of diesel, solar PV and wind). The Hybrid Optimization of Multiple Energy Resource (H...
This paper is written with respect to the modeling of DC Micro grid using solar panel and backup generator by applying Hybrid Optimization Model for Electric Renewable (HOMER) pro software tool to supply cost effective and reliable independent power to a limited number of rural communities that used specific type of DC loads. The model area was selected ahead of the modeling and analysis process and indicated on Map using the HOMER pro area search facility. A generator that used Methanol was added to the system to enable the designed model more reliable. The contribution of each source type was analyzed in detail in the analysis section of the paper. It showed that the contribution of the generator is insignificant as compared to the contribution of the solar panel in supplying the loads. This paper mainly focused in analyzing the primary and secondary simulation data outputs by considering the base and current model systems. The base model system contained the solar panel and battery storage only. Whereas the current model system contained the solar panel, battery storage and generator. The optimal operation shows a unit cost of Rs. 0.125/kWh with the selected energy system with 100% renewable energy contribution eliminating the need for conventional generator. The developed model helped in sizing the components of the energy system and decides the optimal combination for electrification of the rural village in Navamalai, Aliyar region, Coimbatore District, India by DC power. Final conclusion reached based on the identified optimal model and analysis.
Hybrid System Solution for Off-Grid and Rural Energy Access in Indonesia
FoITIC, 2017
Based on a recent study in 2016, there are still 12.659 underdeveloped villages or 16% of the total number of villages in Indonesia are still lacking in electric power from PT PLN (persero). To fulfill the electricity target in these villages, the government has issued the Program Indonesia Terang (PIT/Electrification Program). This program consists of efforts to extend the grid (for villages where PT PLN is present), install mini grid/off grid/hybrid systems, and implement solar home systems. It is hoped that this program will contribute to the penetration of renewable energy into the national energy mix to reach 25% in 2025. Regulation No. 38/2016

The electrification ratio in Indonesia has reached over 90 percent already but it is not easy to attain the rest of people who have not gotten the light because they are living in the scattered and isolated areas over several thousand islands in the archipelago of Indonesia. Conventionally, the electricity service in Indonesia is developed by using a centralized and interconnected of various large scale units of power plants. However, many big project of a large size power plant is currently facing many challenges including land and acquisition, financial closing, complex permit procedures, and right of way for transmission lines. As a result, the cost of such conventional system cannot be offset by the expected efficiency from a better reliability and economies of scale of such conventional system. To address this problem, the School of Technology STT PLN Jakarta, proposes an initiative namely ListrikKerakyatan (LK), which is a simple and small scaleself manage electricity development by local people empowerment using renewable energy available around the communities. After passing several pilot projects, This LK initiative has already successfully implemented in Klungkung District, Bali, using the model, called TOSS (TempatOlahSampahSetempat), stands for localized municipal waste treatment. The pilot project shows that a 30 kW gasifeier genset including its associated unit TOSS for 3 ton of waste is cost around USD 40 thousands, the cost of which is still less than rural funding available from national budget. LK needs relatively little operational cost since its fuel is made from municipal waste.
