Description
Summary:This paper presents a reliable microgrid for residential society with control methods to design grid forming inverter (GFI) to emulate the seamless-synchronization features to deal with the dynamic concerns of the grid. In this microgrid a photovoltaic (PV)-based GFI with a control scheme in parallel with a PV-battery supported inverter with an enhanced current control is considered to operate under non-ideal grid voltage conditions. The PV-GFI is adaptable to operate either in islanded mode (IAM) or grid integrated mode (GIM) depending under the grid conditions. An adapted power control technique is implemented such that power demand of local loads and harmonic currents are compensated by respective distributed generation. Moreover, the active power demand of all local loads is shared between the main grid and respective local DG. The adapted power controller achieves transient free operation even under the load disturbances. The proposed control methods of microgrid are validated in simulation under various operating conditions.
