To meet the large-scale business requirements for distributed photovoltaic(PV)integration,an analysis and evaluation software for an active distribution system with PV is designed and realized in this paper. First,the architecture system of a time series-based analysis model is proposed to adapt the multi-time scale operation simulation analysis of an active power distribution system,including a time series model of PV generation,load and power network. In addition,the idea of hierarchical comprehensive analysis and evaluation for the fine analysis and evaluation of the active power distribution system with PV is also introduced. Then,the overall architecture and main functions of the software are explained using the theory of multilayer architecture based on the information system design methodology. Finally,the validity and practicability of the basic algorithm in the software are verified by an IEEE standard example and an actual distribution system in one area,respectively. Results show that the analysis and evaluation function of the software realized in this paper can better support the comprehensive analysis,evaluation,optimization,and planning of the active power distribution system with PV.
