Sustainable development is an inevitable choice for the development of human society, and energy is closely related to sustainable development. Improving energy structure, increasing energy efficiency, and vigorously developing renewable energy are of great significance to the sustainable development of rural areas. Moreover, the establishment of a distributed multi-energy complementary system (MECS) using abundant renewable energy such as wind, solar, and biomass energy is an effective way to solve the rapid growth of rural power demand, weak rural power grids, and rural environmental pollution. This paper proposes a new type of Wind–Solar–Biomass–Storage MECS composed of wind power generation (WPG), photovoltaic power generation (PVG), biogas power generation (BPG) and energy storage system (ESS) and establishes a MECS optimization operation model with the goal of maximizing daily operating economic benefits, considering the characteristics of each power generation system and power demand characteristics. By using the multi-population genetic algorithm (MPGA), the simulation experiments of the MECS operation under four typical weather scenarios are carried out. The results show that the MECS can operate stably in different scenarios and achieve the goal of maximizing economic benefits, which verifies the feasibility of the MECS model. In addition, the simulation results are compared with the standard genetic algorithm (SGA), which shows the effectiveness of the optimization method. This paper takes Chinese rural areas as an example for research. The proposed MECS and optimal operation model are also applicable to developing countries with a high proportion of the rural population.

In order to improve the power generation benefit of the Tianhu Hydropower Station, a optimal operation model of the water supply system of the power station is built to maximize the gross electric energy generated. The model takes into consideration that Tianhu Hydropower Station has multiple water supply modes and is characterized by its super-high water head, and that any small change on flow control may bring great impact on the output of the power station. Based on existing hydrological data and the optimal scheduling model, the optimized results are calculated and made to optimization curves. These optimization curves are used to guide the operation of the hydropower station. Years of actual practices demonstrated that operating Tianhu Hydropower Station under the guidance of the optimal reservoir group operation model presented in this paper has brought in significant economic benefits, with an annual increase in power generation income of more than eight million yuan.

East African Community

The article analyses the role of renewable energy in the process of the development of the energy market of the East African Community (EAC) . The author underlines the necessity of finding solutions for such challenges as rising wood and charcoal prices, deforestation, lack of affordable and reliable electricity for a large number of consumers. The study reveals that nowadays the percentage of people with access to modern sources of energy is very low, varying from 7 % in Burundi to 36% in Kenya, although the EAC countries made significant progress in 2000s. Most people in rural areas rely on traditional biomass for cooking and heating, which leads to ecological and health problems. The author concludes that renewable energy development is considered by the Community as one of the prospective ways for providing energy to remote regions in view of abundant solar, wind and geothermal resources. Their strategy aims at the construction of micro and mini hydro stations, stand-alone solar PV systems and off-grids for rural population usage. The study shows that the investment in off-grid renewables has been steadily rising in recent times . Analyzing grid-connected power generation electricity, the author elicits that it is also based on renewable electricity, which accounts for 65% of the total amount. Kenya, with the highest installed capacity in this sector, is investing mainly in geothermal, solar and wind sources of energy, while the others are focusing on hydropower and solar. For the purpose of attracting private investment, the EAC partner states adopted different regulations, including Feed-in Tariff, zero-VAT and GET FIT Programme. The author assumes that renewable energy financing is one of the main challenges despite the support of different international financial institutions, such as the World Bank, UNIDO, AfDB and others. Nowadays energy efficiency measures are becoming important instruments for the EAC countries resulted in power savings. The other important trend is increasing cooperation among them due to their grid-connected power systems in the East African Power Pool. In this context, in November 2017, the EAC Partner States adopted Energy Security Policy Framework, in order to ensure the sustainable development of their energy sector.

The goal of power sector in Nigeria is to efficiently and reliably transmit electrical power to all parts of the country which are made up of thirty-six states of the federation and the federal capital territory. The constituents of electrical power system are the generation, transmission, distribution and the utilization of electrical energy. There is gross power imbalance between the generation and the required power demand which has culminated into a defective economy in the last three decades. This paper therefore examines the power imbalance between the generation and power demand by the consumers and therefore stresses the need to harness the opportunity of renewable energy generation close to the gap between the power generation and power demand. This will help in transmitting and distributing efficient, effective, reliable power to consumers and improve both human and capital development. The availability of renewable energy sources such as sun, wind and small hydro power will be explored for the future of power generation in the country to fill in the gap between power generation and demand in Nigeria

Accessing electric vehicle (EV) into micro-grid (MG) by battery-swapping station (BSS) will not only reduce the negative impact brought by EVs which are directly accessed into MG, but also improve the capacity of MG to absorb more renewable energy. That BSS is regarded as schedulable load is guided to avoid peak and fill valley according to TOU. As a result, the gap between peak and valley of MG is decreased and the operation efficiency of MG is elevated. A specific MG is taken as the studying object and the minimum operating cost is regarded as the optimizing goal, then the genetic algorithm is used to optimize the outputting of each micro-source and the charging power of BSS so that the optimal operation is realized.

The Poyang Lake Eco-Economics Zone includes 38 counties where 25 relatively poor counties are close to the lake. The country has been helping those rural areas and enhancing farmers’ living standard for many years, however, due to the historical, geographical, climatic reasons, farmers’ living standards do not have significant improvement so far. In addition to government subsidy, another way to enhance farmers’ income is to encourage of bioenergy production in a form of biochar/pyrolysis. Biochar/pyrolysis is a feasible method to produce clean and renewable energy along with substantial environmental and economic benefits such as increase in farmer’s revenue. However, there are also difficulties in its application due to transportation, feedstock collection, and storage. However, there need further investigation to quantify the gains and losses of pyrolysis/biochar technology.

This paper mainly concentrates on the energy crisis for a long time in Bangladesh. The government is trying its best to overcome this problem. Due to high investment requirement for conventional power plants, responses from the private sector for power generation are very poor. One alternative solution may be the expanded use of renewable energy. At present solar cells are in use for power generation. But due to high initial investment required for solar panel installation, this form of renewable energy has not been practiced much. The aim behind the study is to integrate the architectural planning regarding physical environment and power crisis problem which may lead to an ultimate improvement of socio economic scenario of the country. In doing so the paper proposes a hypothetical model using biogas as a source of renewable energy by using the rural waste-leading to cash from trash.
