“…Although the development of renewable energy has received attention in Africa, the continent's share of renewable energy in total final energy consumption was still on a declining trend [89]. A causal loop diagram using system dynamics (Figure 5) reveals that active national policies, appropriate subsidies, and technical expertise are particularly important in promoting biogas projects in Africa.…”

More than 500 million people will be added to Africa’s cities by 2040, marking the largest urbanization in history. However, nonrenewable fossil energy sources are inadequate to meet Africa’s energy needs, and their overexploitation leads to intensified global warming. Fortunately, Africa has a huge potential for biomass energy, which will be an important option for combating climate change and energy shortage. In this study, we present a typical large-scale biogas plant in Burkina Faso, West Africa (Ouagadougou Biogas Plant, OUA), which is the first large-scale biogas generation plant in West Africa. The primary objective of OUA is to treat human feces, and it serves as a demonstration plant for generating electricity for feed-in tariffs. The objectives of this study are to assess the greenhouse gas reduction capacity and economic, environmental, and social benefits of OUA and to analyze the opportunities and challenges of developing biogas projects in Africa. As a result, the net economic profit of the OUA biogas plant is approximately USD 305,000 per year, with an anticipated static payback period of 14.5 years. The OUA plant has the capacity to treat 140,000 tons of human feces and 3000 tons of seasonal mixed organic waste annually, effectively reducing greenhouse gas emissions by 5232.61 tCO2eq, improving the habitat, and providing over 30 local jobs. Finally, the development of biogas projects in Africa includes advantages such as suitable natural conditions, the need for social development, and domestic and international support, as well as challenges in terms of national policies, insufficient funding, technical maintenance, and social culture.

“…Section 2 has discussed the PPS methodology used to dispatch a certain amount of increment energy Er from LEU to replace several amounts of energy that are supposed to be produced by the thermal unit and the determination of saving utility cost has also been discussed. The constraint in this case study is generator operating limits, wherein every thermal unit and hydro or LEU has their upper and lower production limits, which can be evaluated by Equations ( 21) and (22). As for the transmission line, the constraint is not considered due to simplifying computational procedures into the probabilistic simulation.…”

“…The SUC is obtained based on the generation system, which is usually discussed in terms of their energy and cycling operation and total capacity installation. From the utility perspective, dispatching the limited energy units (LEU) to meet the forecasted load demand over a period of time with certain specified reliability can yield remarkable SUC [20][21][22]. It is important to note that in the least-cost planning or peak-shaving application in the generation system, the optimal dispatch of limited energy units (ODLEU) does not affect in reliability indices or total capacity installation.…”

In the generation of operating system planning, saving utility cost (SUC) is customarily implemented to attain the forecasted optimal economic benefits in a generating system associated with renewable energy integration. In this paper, an improved approach for the probabilistic peak-shaving technique (PPS) based on computational intelligence is proposed to increase the SUC value. Contrary to the dispatch processing of the PPS technique, which mainly relies on the dispatching of each limited energy unit in sequential order, a modified artificial bee colony with a new searching mechanism (MABC-NSM) is proposed. The SUC is originated from the summation of the Saving Energy Cost and Saving Expected Cycling Cost of the generating system. In addition, further investigation for obtaining the optimal value of the SUC is performed between the SUC determined directly and indirectly estimated by referring to the energy reduction of thermal units (ERTU). Comparisons were made using MABC-NSM and a standard artificial bee colony and verified on the modified IEEE RTS-79 with different peak load demands. A compendium of the results has shown that the proposed method is constituted with robustness to determine the global optimal values of the SUC either obtained directly or by referring to the ERTU. Furthermore, SUC increments of 7.26% and 5% are achieved for 2850 and 3000 MW, respectively.
