Active power control of smart grids Using Plug-in Hybrid Electric Vehicle

In conventional power systems, due to lack of communication, power sharing between generators is based on their capacities and economical power flow would not be applied. So, this would be led to rise of fuel consumption and reduced efficiency. For solving this smart micro grid with communication platform is defined. This micro grid consists of load, Plug-in Hybrid Electric Vehicle (PHEV), and Auxiliary Power Unit (APU). APU works in voltage-frequency mode and its role is to fix the voltage and frequency of micro grid. Whereas, PHEVs work in power injection mode and produce power based on the set points that are defined for them. These set points which indicate the contribution of each PHEV in producing power are defined by an economical power flow in a control center known as Central Power Management (CPM). The PHEVs are connected to the Point of Common Coupling (PCC) through Voltage Source Inverters (VSI). Since the active power flow depends on the deference between angles of inverter output voltage and PCC voltage, by controlling this angle deference, active power will be controlled. By comparing the proposed smart method with conventional method, through simulations in MATLAB/Simulink environment, it will be approved smart method is more economical.
