Rule-Base Current Control for Microgrid Energy Management System
Keywords:Current Control, Energy Management System, Microgrid, Rule-Base,
AbstractRule-base current control for Microgrid Energy Management System (EMS) is an idea to managing different micro sources by using rule-base to allow each resource to participate in the Microgrid in prober time when needed. These resources are Photovoltaic (PV), wind turbine (WT), fuel cell (FC), and diesel generator and battery storage. Every source waits for a control signal from the rule-base controller to connect or disconnect from the Microgrid based on preprepared rule bases. Since this Microgrid needs a load, a real load data of 2MW has been collected and involved in the system. This load has been built by Matlab Simlink for 24 hours, wherein each hour was represented by 0.1Sec in the simulation and the power factor was 0.85. The controller has been tested in real residential and industrial load data taken from TNB in Selangor, Malaysia. Represented as Microgrid control signal for each source, rms current signal, and sinwave current signal, the results expressed controller’s behavior when the current decreases and increases.
