Abstract Distributed generator (DG) accessing to smart distribution grids, with the improvement of their permeability, may cause harmonic levels of grid node exceeding the harmonic standards GB and restrict power accessing to distributed power. Study of penetrating level considering harmonic influence is very important. To solve this problem, this paper analyzes the harmonics injecting to grid indeterminately when new energy accessing to grid and analyze the influence of harmonic spreading in grid based on 2m+1 point estimation method. The calculation methods of balance degree index of harmonic margin is proposed based on each node harmonics voltage distribution of the whole network. This paper present a method for maximizing penetration level of DG, modeling in the form of multi-objective mathematical programming to simultaneously minimize balance comprehensive degree index of harmonic margin and maximize power of DG access to grid. In order to solve this model, an augmentedε-constraint considering weight of each objective function method incorporation of particle swarm optimization (PSO-AWCM) is proposed which could optimize more effectively comparing to conventionalε-constraint method. Moreover, fuzzy decision theory is implemented to choose the most preferred compromise solution among the Pareto solutions. Using IEEE33 bus system demonstrate the effectiveness and superiority of the proposed method.
