Modeling of inverter based Ac microgrids for control development

This paper will present the model formulation and testing for the integration of renewable energy into networked ac bus microgrid. This paper presents a model of an inverter based ac microgrid that is appropriate for use in advanced control schemes, such as Hamiltonian Surface Shaping and Power Flow Control (HSSPFC). A two inverter three phase ac system with a wye connected resistor-capacitor load is developed, and an example system is presented. The model development will show the electrical power network transformation from the abc to the 0dq domain. Testing and verification procedures will also be discussed demonstrating its behavior.
