Integrating PV Systems with Battery Energy Storage Systems into Malaysian Medium Voltage Reference Networks for the Applications of PV Power Smoothing and Energy Time Shift
It is important for integrating Photovoltaic (PV) systems with battery energy storage in the distribution network for the enablement of continued uptake of PV system installations. The escalating interest pertaining the environmental and climatic change concerns has encouraged the integration of renewable resources such as PV system into power distribution networks worldwide, which will be essential towards the achievement of a sustainable future. The PV systems development has resulted in a number of concerns which include intermittency of supply, reverse power flow, and voltage rises. Hence, this paper compares the various techniques for solar power smoothing. Moreover, two kinds of BESS models were used in charging the distributed storage units during midday, of which the power from the solar PV would be higher than the load level. The energy that is stored is next utilized for the reduction of the peak load in the evening and early morning. Urban and Rural Malaysian medium voltage Reference Networks (RNs) have been considered, the effect of various configurations of PV systems have been offset with Battery Energy Storage Systems (BESS). From this, combinations of PV and storage that are most effective at mitigating the issues were explored.
