英文摘要：

A dynamic fitness evaluation method is proposed to handle constrained optimization problems.The values of the objective and the constraint violation are both dynamically normalized and summed up with corresponding weights to evaluate the fitness values.The proposed method not only overcomes the difficulty in tuning the coefficients of penalty function,but also increases the diversity and global search ability of the optimization algorithm.It is applied to the particle swarm optimization algorithm to solve the optimization problem in micrositing a wind farm.Simulation results demonstrate that the power generated by the wind farm is increased,so is the efficiency of wind energy exploitation.Moreover,the proposed method can be widely applied to other optimization algorithms to solve constrained optimization problems.
