Analysis of hybrid photovoltaic and wind energies connected to unbalanced distribution systems

This paper presents a steady state analysis of allocation of photo-voltaic and wind generation units in electrical distribution networks. A complete steady state models for PV energy power generation systems for power flow applications is applied. In addition, a new model for the induction generator for wind generation unit will be presented. These models are driven without any assumption and by taking into consideration complete generation system equivalent circuits parameters. It is noticeable that the input data for these driven models are only the environmental conditions. In addition, different load models, capacitor banks, distribution transformer and voltage regulators are also implemented with any number of phases and connection. This Analysis is performed to identify issues that will be most relevant to engineers working in planning and operations of distribution systems with installed distribution generation. Comprehensive tests are applied on 123 node IEEE distribution test system.
