“…Utilizing an equilibrium optimizer algorithm to determine the optimal hub height for some wind turbines to maximize wind power at the lowest total cost, the feasibility of using wind resources and the economic valuation of four sites in Egypt-Ras El-Hekma, Farafra, Nuweiba, and Aswanwere studied in two stages. The energy cost of these turbines was calculated and compared with the global and Egyptian economies [6].…”

The 2022 United Nations Climate Change Conference (COP27) recommended that Egypt be converted to green energy, in addition to increasing the demand for annual energy consumption, which will lead to an increase in the use of renewable energy sources (RES) in Egypt. The Egyptian Ministry of Energy and Electricity plans to build RES (photovoltaic systems and wind farms) connected to the Egyptian power system (EPS). It is a defect to choose the position and size of the RES based on only power calculations because the RES is an intermittent source. This paper presents a modified analytical energy technique for locating RES in IEEE 33-bus and 69-bus distribution networks and a realistic 25-bus 500 kV EPS. An analytical multi-objective function has been developed to determine the optimal locations of DGs or RESs based on power losses and annual energy loss calculations of the system depending on weather conditions. The efficiency and feasibility of the proposed algorithm based on the IEEE 33-bus and 69-bus distribution networks and the realistic 25-bus 500 kV EPS have been tested and compared with PSO and GA. The impact of RESs on the performance of the 25-bus 500 kV EPS has been investigated based on annual energy losses and operation stability depending on weather conditions. The results showed that the proposed technique used these effective values to obtain optimal weather-adjusted locations. The optimal locations of PV systems or wind systems based on energy calculation improved the voltage profile better than power calculation by about 2%, and the annual energy losses decreased by about 7%. The performance of the 25-bus 500 kV EPS, due to the addition of RES, resulted in a decrease in the annual energy losses of 47% and an improvement in the voltage profile and system stability.

Carbon emissions pose a massive risk to our planet's health. According to the Paris Climate Agreement, nations pledged to limit global warming to 1.5°C to mitigate climate change's impacts. This target will not be achieved without immediate and deep emissions reductions across all sectors. Unfortunately, the Russian-Ukrainian conflict and the new natural gas discoveries in some countries have also slowed down the pace of decarbonization. Aside from that, a faint light at the end of the tunnel could be seen from the new Intergovernmental Panel on Climate Change (IPCC) report, which pointed to increasing actions on climate change. Fortunately, achieving future zero carbon emission is still possible via the implementation of holistic frameworks that promote existing and emerging green technologies and helps the community to transform. This policy paper proposes a framework that integrates technology use and mobilizes the transformation of communities' mindsets to cope and adapt to climate change. The proposed framework will then be implemented in the country hosting the 27th Conference of the Parties of the UNFCCC (COP 27), Egypt, and it is recommended to be used by scholars and policymakers for future assessment of the country's climate change performance. Finally, the paper provides a set of recommendations to governments, policymakers, and communities to accelerate the movements toward a net zero-carbon future.

“…The algorithm is mainly inspired by the control volume mass balance model. Compared with other heuristic optimization algorithms, the EO algorithm effectively balances the relationship between exploration and exploitation and has attracted extensive attention since its appearance (Ahmadipour et al, 2022;Wang et al, 2021;Soliman et al, 2021;Alham et al, 2022). The optimization principle of the EO algorithm is similar to the PSO algorithm.…”

With the urgency of environmental protection, wind power and photovoltaic (PV) projects are continued to be implemented, and the proportion of renewable energy in the power grid will be higher and higher. Therefore, wind power and PV also began to participate in the regional power grid frequency regulation (FR) and have gradually replaced the role of thermal power units in the power grid. To study the characteristics of renewable energy in frequency modulation, an automatic generation control (AGC) model of wind power and photovoltaic participating in the power grid FR is established. At the same time, an equilibrium optimization is proposed to allocate the total power in real-time so as to improve the FR performance by quickly obtaining the optimal power distribution scheme. The simulation results of the proposed model show that the proposed method is feasible. At the same time, the proposed method is compared with the genetic algorithm (GA), which proves the superiority of the proposed method.
