Project Details


High Penetration of Photovoltaic Generation Study - Flagstaff Community Power High Penetration of Photovoltaic Generation Study - Flagstaff Community Power The main objectives of this area are to develop and validate the models and analytical tools required to study the impact of high penetration PV (Hi-PV) on the design, operation, safety and performance of typical distribution systems under various operating scenarios. The models and simulations will serve three major purposes (1) serve as a design tool for the proposed Flagstaff demonstration project and (2) serve as a tool for studying various what-if scenarios corresponding to different contingencies, PV penetration levels and customer demands, which cannot be practically tested on the real system but need to be accounted for in the design of an actual system, and (3) to study the extrapolation of proposed approaches to much larger distribution system with more advanced, smart-grid features. The modeling thrust consists of three distinct but interdependent layers. Layer 1 represents the development of analytical models for the critical physical components or sub-systems of a power system with high penetration of PV generation. Different types of models with a wide range of complexity suitable for different study objectives will be developed. Layer 2 corresponds to the actual analytical and simulation studies using the above models (and model based design of hi-PV systems) to understand the impact of Hi-PV for various conditions, and model-based design of various components of the demonstration system. This will also be used to extrapolate the understanding gained to much larger power systems. Layer 3 corresponds to validation of the developed models by comparing the analytical/simulation results with actual field test results. A main feature of the proposed approach as indicated in Fig. 1 is that the models will be continuously refined over the 5 year duration of the project through comparison with different stages of the field testing.
