Optimization of a Small Wind Power Plant for Annual Wind Speed Distribution

Abstract

This article presents a method to adjust the elements of a small wind power plant to the wind speed characterized by the highest annual level of energy. Tests were carried out on the basis of annual wind distributions at three locations. The standard range of wind speeds was reduced to that resulting from the annual wind speed distributions in these locations. The construction of the generators and the method of their excitation were adapted to the characteristics of the turbines. The results obtained for the designed power plants were compared with those obtained for a power plant with a commercial turbine adapted to a wind speed of 10 mps. The generator structure and control method were optimized using a genetic algorithm in the MATLAB program (Mathworks, Natick, MA, USA); magnetostatic calculations were carried out using the FEMM program; the simulations were conducted using a proprietary simulation program. The simulation results were verified by measurement for a switched reluctance machine of the same voltage, power, and design. Finally, the yields of the designed generators in various locations were determined.

Recent Development in the Design of Wind Deflectors for Vertical Axis Wind Turbine: A Review

“…Small-scale wind power generation is not as popular as large-scale wind power; searching for "small winds" in the database of MDPI found 59 research articles, only, compared to 900 for "wind power" or "wind energy" for the same period from 2010 to 2019. Lack of interest towards small wind systems for decades resulted in highly counterproductive VAWTs, lower efficiency, and hence, high costs per kilowatt [57,58]. The development of smart grids and distributed energy systems is spurring renewed interest in small energy again.…”

“…These techniques can lower per-kilowatt prices for small-scale wind generation, which could be a basis for its popularity in the near future. More work and research on large-scale wind generation has resulted in a surprising decrease in prices during the past 15 years [58,65]. Likewise, if the research in small wind energy continues, engineers will find it more attractive to harness energy from small wind sources.…”

Optimal Sizing of Energy Storage System for Operation of Wind Farms Considering Grid-Code Constraints

“…The factor φ is the capital recovery factor representing the weights between the four types of costs, as given in (7). The second term of (6) shows the penalty of shortage power in the limited power mode due to wind uncertainty. The third term of (6) shows the penalty for the shortage of reserve capacity in the reserve power mode.…”

“…The third term of (6) shows the penalty for the shortage of reserve capacity in the reserve power mode. The fourth term of (6) shows the profit by selling power from WFs to the power system. The coefficients α, β represent the weight of each grid-code constraint in the operation of W. Equation ( 8) is used to compute the total cost of the power conversion system using the rated output power of the ESS (P) and the unit cost of power electronics.…”

“…The WF system is operated by an energy management system [3][4][5] to achieve the common objectives for the whole WF system. For instance, an optimization method is proposed in [6] to adjust the set-points of WTGs for maximizing the output power of the entire system.…”
