The electric grid is now transforming into a hybrid distributed network. This situation calls for a robust and reliable energy management strategy for effective and reliable grid integration of distributed energy sources. This paper aims in addressing ideal loss of power supply probability in a solar PV and battery (EV fed) grid-integrated system with AC loads. Bidirectional power flow is realised through means of bi-directional inverter operating at a power rating of 2000 W. The surplus energy generated by the considered PV system is effectively managed to supply the AC load and the battery employing a state flow-based energy management strategy. During grid-connected and islanded mode, the state of charge of the battery is maintained between a range of 50–70% of the nominal power capacity. The battery voltage is also regulated to a constant value equal to its rated voltage capacity of 240 V. The state-flow approach of the proposed energy management system supports three modes, namely the PV mode, grid mode and RES mode. Efficient grid synchronisation is also achieved through the phase synchronisation of inverter output voltage and the three-phase grid current leading to unity power factor operation. The total harmonic distortion of the inverter output voltage synchronised with the grid is as low as 0.08% proving the effectiveness of the proposed approach.
