Pay-As-You-Go financing: A model for viable and widespread deployment of solar home systems in rural India
摘要： Decentralised Solar Home Systems (SHSs) are established as an effective strategy to connect the ‘last mile’ without electricity access and leapfrog communities to clean energy solutions. According to the World Bank, the Pay-As-You-Go (PAYG) model has emerged as one of the effective commercially viable solutions to provide decentralised energy access to rural and remote communities in developing nations. The paying ability of households is a critical challenge for energy enterprises, and PAYG, with its easy payment schemes makes solar units affordable and allows households to gradually own these systems. The model also offers user training, ongoing maintenance, and service blocking functionality that minimises investment risk. The PAYG model has demonstrated huge success in Sub-Saharan Africa where Kenya pioneered the model as a cost competitive modern alternative for kerosene. One in five people in India lack access to electricity, and grid-connected rural communities often face frequent blackouts. With the advancement in distributed solar technologies and growing penetration of the mobile telecommunications network in India, PAYG could advance into a successful model to electrify communities living off the grid. Our analysis involves a two-dimensional approach where a systematic review of PAYG literature including case studies from Kenya and India was performed, followed by three expert interviews to further augment learnings and opportunities to deploy PAYG SHSs in India. This analysis finds that India's socio-political context seems suited for increased PAYG penetration, including utilising the opportunity provided by the country's Unified Payments Interface. This paper offers insights for practitioners and policymakers to consider the PAYG model to deploy clean electricity to households and rural micro-enterprises.

[IEEE 2018 53rd International Universities Power Engineering Conference (UPEC) - Glasgow, United Kingdom (2018.9.4-2018.9.7)] 2018 53rd International Universities Power Engineering Conference (UPEC) - Feasibility Study for a Solar PV Microgrid in Malawi
摘要： Energy is an enabler for development but electricity access is still unobtainable for over 1 million people in developing countries. In Malawi, less than 12% of the population have access to grid electricity and in rural areas this is as low as 1%. Solar microgrids are emerging as a cost competitive, low carbon and reliable method for offering energy access in developing countries. This paper provides a summary of the process and key findings in assessing technical and financial feasibility of a solar microgrid in Malawi, including system design definition, business model discussion and sensitivity analysis of key parameters through techno-economic modelling. The novel approach developed utilises qualitative and quantitative information gathering and assessment in an iterative way to design a robust energy access solution in the most viable local location. The results show that the upper limit of the ‘expected energy use’ can be up to 5 times higher than the designed energy limit. Higher demand grids are shown to present c.20% lower levelised cost of energy for the cases considered and conversely, the ‘low demand’ grid case is shown to have c.48% higher levelised cost of energy. This represents a significant range of uncertainly in energy use prediction, which if not treated properly will adversely affect both energy access and microgrid business development. The research presented in this paper will address these challenges in the context of Malawi but is broadly applicable to other similar locations.

A Methodology to Develop Design Support Tools for Stand-alone Photovoltaic Systems in Developing Countries
摘要： As pointed out in several analyses, Stand-Alone Photovoltaic systems may be a relevant option for rural electrification in Developing Countries. In this context, Micro and Small Enterprises which supply customized Stand-Alone Photovoltaic systems play a pivotal role in the last-mile-distribution of this technology. Nevertheless, a number of issues limit the development of these enterprises curbing also potential spinoff benefits. A common business bottleneck is the lack of technical skills since usually few people have the expertise to design and formulate estimates for customers. The long-term solution to tackle this issue implies the implementation of a capacity building process, but this solution rarely matches with time-to-market urgency of local enterprises. Therefore, we propose in this study a simple, but general methodology which can be used to set up Design Support Tools for Micro and Small Enterprises that supply Stand-Alone Photovoltaic systems in rural areas of Developing Countries. After a brief review of the techniques and commercial software available to design the targeted technology, we describe the methodology highlighting the structure, the sizing equations and the main features that should be considered in developing a Design Support Tool. Then, we apply the methodology to set up a tool for use in Uganda and we compare the results with two commercial codes (NSolVx and HOMER). The results show that the implemented Design Support Tool develops correct system designs and presents some advantages for being disseminated in rural areas. Indeed it supports the user in providing the input data, selecting the main system components and delivering estimates to customers.

Solar Energy, dc Distribution, and Microgrids: Ensuring Quality Power in Rural India
摘要： Ensuring quality power in rural India. As the Leisang village in Manipur received electricity in April 2018, the prime minister of India announced that every Indian village is now electrified. A village is considered electrified in India when 10% of its homes receive electricity. However, the number of village homes that have electricity has now reached 84%, with some 41 million households still without power. This village-electrification program has been going on for many years. Until a few years back, there was a large shortage of power with power demand exceeding supply, leading to no/a weak push to extend the grid to the village. Over the last few years, when more coal power plants became operational, the supply strengthened. At the same time, the energy costs for the solar and wind power-attained grid parity, enabling the addition of significant renewable power. Simultaneously, the power grid was strengthened, and India attained a single national grid on 31 December 2013, such that power generated in surplus areas could be transported to deficit regions. All of this helped in surplus power generation because the demand did not pick up much in recent years. The social obligation to extend the electric grid to each village and then to at least 10% of its homes no longer had a fundamental bottleneck. The target-driven approach of the prime minister’s office helped to expedite the effort.

Scalable Solar dc Micrigrids: On the Path to Revolutionizing the Electrification Architecture of Developing Communities
摘要： There is a worldwide focus on the electrification of developing regions, as is evident from the sustainable development goals (SDGs) of the United Nations. In particular, the aim of SDG 7 is to ensure universal access to affordable, reliable, sustainable, and modern energy services for all by 2030. Because of these sustained efforts, more than 1 billion people worldwide have gained access to electricity since 2000. During this course, the electrification architecture of developing regions has taken different forms, ranging from extensive utility grid extensions to limited off-grid solutions. Off-grid solutions generally offer cost-effective and lower up-front cost alternatives in comparison to utility grid extensions and are deemed more suitable for developing economies. In developing economies, these off-grid electrification solutions have evolved from individual solar home-based systems to community-based microgrids in pursuit of achieving higher efficiency and reliability on a village scale. Community grids responsible for the electrification of developing regions are further categorized based on architecture, type of generation, and mode distribution.

Potential, optimization and sensitivity analysis of photovoltaic-diesel-battery hybrid energy system for rural electrification in Algeria
摘要： Integration of hybrid renewable energy systems (HRES) as an electrification solution can enhance the rural electrification situation in Algeria's predominantly remote Saharan regions, where diesel generators are used to provide very basic and limited electricity service. The exploitation of such a solution requires a sustainable, optimized HRES design. This paper presents a methodology both to optimize and to perform a sensitivity analysis of an autonomous hybrid PV-diesel-battery energy system. Particle Swarm Optimization (PSO) and ε-constraint method were used to simultaneously minimize total system cost, unmet load, and CO2 emissions. One optimal solution was chosen among the solutions set and analyzed. The remote Saharan village of Tiberkatine, province of Tamanrasset in southern Algeria was considered as a case study. The hybrid system supplied the energy demand of 20 households. It was found that the optimal solution can supply energy without unmet load, the minimum cost of energy COE is 0.37 $/kWh with 93% renewable fraction. A sensitivity analysis was performed on the optimal system to study the impact of three parameters (load consumption, εCO2, and εLLP constraints) on the system behavior. Finally, a comparative analysis between PSO and HOMER was performed, it was found that the PSO based approach is more cost effective with more PV penetration than HOMER.

Long, Cheras, Kajang, Malaysia (2018.5.29-2018.6.1)] 2018 International Conference on Smart Grid and Clean Energy Technologies (ICSGCE) - Improving Rural Electrification through Interconnected Solar Micro Grids
摘要： Renewable energy based rural electrification system experiences fluctuation in generation efficiency due to various unpredictable dynamic changes such as solar irradiation levels, rainfall, dust accumulation, vegetation, etc. Due to these fluctuations the system experiences frequent power quality issues such as low voltage, power interruptions, operating the degradation of the performance and reliability of these solar micro grid systems. In this paper micro grid cluster interconnection methodology is proposed to improve the efficiency of the system. To develop real-time decisions on energy management and micro grid interconnections, we have designed an IoT system that is capable to monitor and learn the dynamic changes in power quality to control the subsystems for improving the quality of service. In this work we have analysed the need of such a system in one of the rural community having solar micro grid deployment in South India. Based on the needs we have designed and developed an end-to-end system consisting of perception layer, network layer and application layer. Detailed experimentation and laboratory and the evaluation was performed performance results are discussed in this paper.
