Awarded
Y Twyni PV and Battery Installation Works
Descriptions
Swansea UNI/Active Building awarded GES to carry out tender works on a R & Dproject encompassing a commercial rooftop solar PV scheme, a carport solar PVscheme, a Battery Energy Storage System (BESS) and EV car chargers located at theSwansea University Bay Campus. The objective of the proposed scheme is to enhancehe sustainability of the buildings reducing the building dependence on expensive andless carbon efficient fossil fuel derived energy imported from the national grid anddetermine the best control schema between each of the elements to optimise the PVgenerated green energy best. A bespoke control system (Schneider MicrogridController) will control the distribution of PV generated power between the BESS,School Of Management (SOM) Building and EV chargers.The Y Twyni building is located centrally on the Bay Campus, Swansea and is adjacento the School of Management (SOM).The Y Twyni will be the platform to locate the rooftop PV system, however, the PVgenerated energy will not supply the Y Twyni directly, a Distribution Board panel at theY Twyni building will connect and route PV power to the SOM building via the BESSsystem. The BESS system will be connected to the SOM and EV chargers, the control ofhe power from the BESS will be via the schneider control system (location in commsroom in the School of Management Building).A zero MEC G99 grid connection will be required as a regulatory requirement forbehind the meter generation. The zero MEC will be associated with the SOM MPRN (LVconnection). The Contractor shall install a G99 Protection Relay and a G100 ExportLimiting Device (ELD) in Control Panels at an appropriate location.Charge and discharge cycles of the BESS will be determined from the EV demand andalso the capacity of the BESS.The following is the control order for the PV generated power from the Y Twyni PV roof,he carport PV and the BESS system.Battery Energy Storage System Order of Distribution (where does power go priority)1. EV Chargers2. SOMThe control of above will be by the Schneider Microgrid Controller.The proposed Single Line Diagram is included in Appendix G.The project is planning exempt for the commercial rooftop solar scheme.
