Considering that the need for electricity is constantly increasing, a crucial problem is the lack of new power facilities. Likewise, due to the large expansion of existing consumption, one of the primary tasks is the reconstruction of existing facilities. Due to their complexity, such problems cannot be solved unplanned, but the development of adequate system solutions must be planned. The biggest problem in finding such solutions is matching both companies and consumers needs. The best way to do this is to develop mathematical models that can meet the already mentioned needs. The development of such models is not a simple task, considering that the final solution is influenced by a number of factors, many of which have a random nature. Therefore, the use of stochastic optimization methods is imposed as a realistic basis for the development of such models, as it is the case in the model presented in this paper. Considering that voltage unbalance is one of the mentioned influential factors, this paper will give the answer to the question whether it has a significant impact on the final solution of the developed model.

“…FEM analysis has the aim to evaluate the objective vector (i.e., the amplitude of the induced voltage and its THD, the mass, and the cost of FSPM generator) related to each hypothesized feasible solution x ¼ N s ; N r ; w ts ; w tr ; w PM ½ , obtained varying the design variables within X. In other words, the FEM analysis realizes the relation between the constraint set X and the attained set Y defined in (25). Moreover, the FEM analysis gives also other electromagnetic performances of the machines.…”

“…Then, the optimum stator and rotor poles number for the generator are achieved according to optimization analysis. It should be mentioned that this investigation is done for small wind turbine generators, but the results could be used as a guide for MW‐class wind turbine, where the mass is the important matter and many studies are carried out to find the best way for lifting up the generators . Obviously as explained before, the other design variables have been keeping constant.…”

SUMMARYCompared with different types of renewable energies, wind energy has the fastest annual growing rate over the last decade. Hence, employing a framework based on numerical algorithms for optimal design of electrical generator, especially adopted for wind power systems, is a great challenge in electrical systems. Recently, for their rigid structure, high torque density and lower mass of the flux-switching permanent magnet (FSPM) generators have attracted much interest because they are capable of supplementing conventional permanent magnet synchronous generators. In this paper, a new analytical hierarchy process (AHP) approach is proposed for a multi-objective optimization of the design of the FSPM generator. To carry out the optimization, trade-offs are considered among more conflicting targets (cost, mass, and some electromagnetic performance). Finite element method numerical results, experimentally validated by means of a prototype, have been used to assess the required data for the optimization. Then the optimal solutions given by the AHP method have been compared with the solutions obtained using different classical optimization methods. The results showed that the AHP approach gives the best solution with respect to the earlier designs and also with respect to other conventional optimization methods, confirming its effectiveness to be used in the optimal design of electrical machines.
