A hybrid microgrid and its co-ordination control with Real- time pricing algorithm
AbstractThis paper presents a hybrid AC/DC micro grid which will reduces the process of several reverse conversions in an individual AC and DC grid. The renewable sources such as wind generators, photovoltaic panels and fuel cell are connected to a hybrid grid. AC sources and loads are linked with AC grid and DC sources and loads are linked with DC grid. The proposed hybrid grid operates in a grid-tied or autonomous mode. Both AC and DC networks are connected by a multi- bidirectional converter. This multi-bidirectional converter operates in parallel with AC and DC grid. Hence, demand over an individual grid can be coordinately controlled by multi-bidirectional converter. The real-time pricing algorithm is proposed. Real-time pricing provides a benefit to the subscriber by providing an optimal cost of power to the load. A hybrid grid has modeled and simulated using the Simulink in the MATLAB. The simulation results show that the system can provides uninterrupted power, smooth power transfer between AC and DC link and also manage the demand.
