This paper develops a new algorithm,called self adaptive evolutionary programming,based on combination of general evolutionary programming and randomized techniques.The new algorithm includes two important procedures,for the first,the expression designed for standard deviation (σ) is inverse exponent,and the second,the amount of mutation (δ) is self adaptive during the optimization.The developed algorithm is applied to multi objective optimal operation of power system for the first time in this paper.Some corresponding technical problems,such as model optimized,genetic operation et al are investigated into.The proposed method is illustrated and tested on IEEE 30 bus system, Numerical results show that the proposed method can bring about some good results on dealing with constraints flexibly,and reducing the computational requirements,and preventing the search from being in local optima or converging difficulty near the global optimum.
