“…It is also necessary to adapt the needs of farmers to the local conditions and respect farmers' living habits, improve the accessibility and affordability [58]. Second, through the biogas and briquetting of biomass energy, and the integration and utilization of electricity coupled with other renewable energy sources such as solar energy, one can better optimize the connotation and applicability of the BBE model [59]. Third, combined with the project's own attributes and choosing the most suitable biomass energy use in rural areas, the optimal path of domestic energy use in rural areas is sought under the premise of economic and environmental sustainability.…”

China’s coal-based energy structure is the main reason for the current high-level air pollution and carbon emissions. Now in the North China Plain, the government is vigorously promoting “coal to gas” and “coal to electricity” in the country and the vast rural areas. The development and utilization of biomass resources in agricultural areas is also an effective means of replacing coal. We propose the idea of forming a complementary rural energy structure of “biogas, briquetting, electricity (BBE)” model based on centralized biogas production (CBP) and straw briquetting fuel (SBF) to improve the rural energy structure. This article uses emergy analysis methods to analyze actual cases. It needs to have strengths and avoid weaknesses in mode selection. The process of the analysis reveals the disadvantages and improvement measures. Under the current capacity load, the emergy input and output, eco-economic indicators, sustainable development indicators, environmental load indicators, and economic value have their own advantages and disadvantages. Assuming 100% capacity load, the indicators have great optimization space. Reducing labor input during the planting phase can effectively reduce emergy input. The government needs to provide corresponding support based on the strengths and weaknesses of the project to keep the project sustainability. The development of complementary integration based on local conditions is an important measure to optimize the energy consumption structure in rural areas and improve the ecological environment.

“…HOMER software was used in [7]- [19] to determine the optimal capacity of hybrid energy sources to quantify techno-economic benefits. Hybrid power system was simulated with hybrid energy sources in China [7], Nigeria [8], [13], Saudi Arabia [9], [19], Iran [11], Turkey [14], and India [10], [17] to evaluate technical-economic benefits. The feasible solution was obtained based on the minimum cost of energy (COE) among different configurations of PV/battery energy storage system (BESS)/WT/fuel cell energy sources in Saudi Arabia [12].…”

Microgrids with hybrid renewable energy sources are increasing and it is a promising solution to electrify remote areas where distribution network expansion is not feasible or not economical. Standalone microgrids with environment-friendly hybrid energy sources is a cost-effective solution that ensures system reliability and energy security. This paper determines the optimal capacity, energy dispatching and techno-economic benefits of standalone microgrid in remote area in Tamilnadu, India. Microgrids with hybrid energy sources comprising photovoltaic (PV), wind turbine (WT), battery energy storage system (BESS) and diesel generator (DG) are considered in this paper. Various case studies are implemented with hybrid energy sources and for each case study a comparative analysis of techno-economic benefits is demonstrated. Eight different configurations of hybrid energy sources are modeled with renewable fractions of 50%, 60%, 65%, and 100%, respectively. The optimization analysis is carried out using Hybrid Optimization Model for Electric Renewable (HOMER) software. Impact of demand response is also demonstrated on energy dispatching and technoeconomic benefits. Simulation results are obtained for the optimal capacity of PV, WT, DG, converter, and BESS, charging/discharging pattern, state of charge (SOC), net present cost (NPC), cost of energy (COE), initial cost, operation cost, fuel cost, greenhouse gas emission penalty and payback period considering seasonal load variation. It is observed that PV+BESS is the most economical configuration. COE in standalone microgrid is higher than the conventional grid price. The results show that CO 2 emissions in hybrid PV+WT+DG+BESS are reduced by about 68% compared with the traditional isolated distribution system with DG.

“…Equation (4) states that the demand for electricity will be satisfied by renewable resources and grid connection. Equations (5) and (6) show that the renewables are primarily used for satisfying demand and if the supply of renewables are inadequate, grid supply is used. Equation (7) defines the renewable energy plant generation capacity.…”

Hybrid energy systems are considered as a potential solution for sustainable energy supply for small and medium scaled energy networks. This kind of energy systems consist of different type of conventional and renewable resources and classified into two groups, stand-alone and grid-connected systems. To see benefits of hybrid energy systems, making operational decisions analytically is extremely important. The main aim of this study is to determine operational decisions of a hybrid energy system by considering profit obtained by system operations and renewable energy utilization ratio in load demand satisfaction. To solve the mathematical model of this multi-objective optimization problem, a goal programming model is proposed in this study. A numerical example for a small town with 10 demand points and 4 energy generation plants is presented to demonstrate the applicability of the proposed model. Electricity demand in the small town is satisfied by energy generation plants and grid-connection. Obtained results show that the proposed model can be used by investors to analyze profitability of the system and renewable energy utilization ratio in the region.
