The impact of grid-connected photovoltaic source on traditional distribution network is analyzed from the aspect of capacity penetration and its limit considering the base load of traditional distribution network is researched.The variation trend of photovoltaic utilization and cost following the increase of gridconnecting photovoltaic capacity is researched from the aspect of energy penetration,based on which,it is proposed to apply the techniques of load transfer and energy storage to enhance the grid-connecting photovoltaic capacity.Simulative results show that,the proposed measures improve both photovoltaic energy penetration and photovoltaic utilization,and the energy storage technique is better,especially when the energy penetration is high.
