PhD: Energy Arbitrage with PV Generation and EV Charging


Project Description:

Queen’s University Belfast has a one remaining PhD opportunity relating to the integration of energy storage into electrical power systems. This opportunity is funded by the Storage Platform for the Integration of Renewable Energy (SPIRE 2) INTERREG VA, a collaborative project led by Ulster University with Strathclyde University and Dundalk Institute of Technology as the other academic partners.

Project Details: Energy arbitrage with PV Generation and EV Charging

The uptake of PV generation at domestic level, largely due to renewable incentives, is giving rise to technical challenges in the operation of the distribution system with significant generation infeed during the day when load it typically small.  Such installations generally fall under DNO’s “fit and inform” policies and therefore DNOs generally respond reactively to any issues that arise.  Moreover, it has been identified that Low Carbon Technologies (LCTs) will generally cluster in geographic area, exacerbating any issues arising.

Additionally, form an owner/operators point of view there is presently a 3 fold financial benefit of using units generated on site as opposed to exporting to the grid.  The objective of this project will be to explore the role of battery storage (~10 kWh) at the domestic level, charging via PV and then discharging when there is sufficient load with the premises.  With the anticipated uptake of EVs, this provides one such load suitable for energy arbitrage.

This project will also seek to model an area of distribution network and to explore the technical challenges associated with significant deployment of these new generation and load technologies for various combinations i.e. PV only, Battery only, PV and Battery; specifically focusing on the impact on thermal, voltage, fault level and power quality aspects of such installations.  Based on these findings, intervention thresholds for typical LV circuits/substations should be identified.  This project will also identify the extent to which energy arbitrage and/or contractual relationships with the DNO has the potential to alleviate such problems.
