Solving optimal Power flow problem with stochastic wind–solar–Small Hydro Power using barnacles mating optimizer
Control Engineering Practice, 2021Co-Authors: Mohd Herwan Sulaiman, Zuriani MustaffaAbstract:Abstract Optimal Power Flow (OPF) is a complex and challenging problem in Power system that includes non-convex and non-linear constrained optimization problems. Due to these features, solving the OPF problem is becoming a well-known area to be solved by researchers for the past decades especially involving with the proper optimizing of the control variables. This issue is vital to be solved in achieving the objectives while maintaining of the stability of the system. In this paper, recent metaheuristic algorithm namely Barnacles Mating Optimizer (BMO) will be used to solve three objective functions of OPF problem viz. (1) cost minimization of the Power generation that consists of thermal and stochastic wind–solar–Small Hydro Power generations, (2) Power loss minimization, and (3) combined cost and emission minimization of mentioned Power generations. To assess the performance of BMO into OPF problem, modified IEEE 30-bus and IEEE 57-bus systems that incorporate the stochastic wind–solar–Small Hydro Power generators will be employed. Statistical studies are performed to show the feasible and effectiveness of BMO compared with other selected metaheuristic algorithms. Based on the obtained results, the BMO has shown the best results for all cases of simulation study. For example, the cost of Power generations obtained by BMO for IEEE 30-bus and IEEE 57-bus systems are 789.1248 $/h and 5300.457 $/hr, respectively which 1.45% and 2.2% cost saving per hour compared to the worst results obtained from compared algorithms. The results suggest that BMO performs better compared to the rest of algorithms and demonstrate as effective alternative for the OPF problem solution.

case study of upgrading potential for a Small Hydro Power station
Renewable Energy, 2005Co-Authors: Karin Thorburn, Mats LeijonAbstract:Schemes for upgrading Hydro Power are formed in many parts of the world. Small Hydro Power (<15 MW) constitutes a fraction of all Hydro Power, but upgrading can still be worthwhile. In this article, a Small generating station in Sweden, with two generators, is simulated with new generators. The voltage is increased by introducing a cable wound stator, thereby the transformers can be excluded, and more efficient generators are introduced with a higher Power factor. These improvements lead to an active Power increase from 8.9 to 9.4 MW per generator, which means an increased total annual production by 4.2 GW h.

Harnessing the potential of Small Hydro Power in Cross River state of Southern Nigeria
Sustainable Energy Technologies and Assessments, 2020Co-Authors: Kenneth E. Okedu, Roland Uhunmwangho, Mathias OdjeAbstract:Abstract Recently, the use of Hydro Power as a renewable energy source, to provide Power solutions is on the rise. Currently, one-fifth of the global electricity generation is from Hydro Power technology. In this study, the potential of harnessing Small Hydro Power (SHP) in Cross River State of the southern part of Nigeria is presented, considering the different sites of Hydro Power in the entire state. The concentration of SHP potential sites is skewed heavily towards regions with hills and forest cover. The cost of the SHP project in this work is based on Power potential of flow at the lean season, however, the actual cost was established based on the extracted peak seasonal Power. In the ranking of the sites for the study, Power potential and cost were used as criteria. The recommended top three sites based on the ranking of the SHP projects were: Kwa Falls, located in Akamkpa, Kundeve stone market stream, located in Obanliku and Ajasor mission Atang stream, located in Etung. Other criteria used for the selection of sites for development includes: isolation from the grid, high cost of transmitting Power from the grid to such communities, economic potential, population and development goals of the government.
