A SIMULATION GUI FOR RENEWABLE GRID INTEGRATED SYSTEM ASSESSMENT

摘要

This paper presents a design of simulation software for performance and economical assessment of Distributed Renewable Energy Systems as they get integrated in the utility power grid system. The simulation system aims at providing technical support to systems of integrating renewable energy resources of PV and WT at the Residential, Commercial and Industrial electric load levels. The system considered is based on a typical integrated configuration that combines a grid-connected, battery-based PV and/or WT integrated system, and operates on a concept of storing energy in the batteries when the utility rate is low and using this power locally when the rate is high. The model used in the simulation system includes techniques developed to optimize the photovoltaic (PV) power and wind energy generation as well as to maintain proper operation with grid system. The simulation software also provides an economical feasibility assessment of the renewable resources to be used, and has been developed in MATLAB environment [8]. It includes an effective Graphical User Interface (GUI) for the simulation system utilization. The GUI includes a panel that is designed and incorporated in an executable program that provides effective and easy graphical interactions to access the powerful mathematical simulation models used for different system components. A case study is presented to show the effective features of the simulation system.
