Abstract/Summary:

---

Solar generation is a prominent source of renewable energy and a rooftop Photovoltaic (PV) system has been deployed in shipyard to generate electricity from the highest irradiance, which is in Tuas, West Region of Singapore. This is based on industrial rooftop PV system which compares Contracted Capacity Charge (CCC) with bigger capacity of Battery Energy Storage System (BESS) in grid-connected PV system, is able to achieve greater cost saving for electrifying to load. This whole system is then modelled with simulation to demonstrate using discharging characteristics of the BESS under six different connection scenarios. The transient stability of PV with greater capacity of BESS can improve quality of the power flow to load when there is a sudden loss of power from PV. In addition, result shows that power quality will vary if there is more capacity in BESS integrated with PV.
