The Customer Led Network Revolution Project

1

Future Challenges

• CO2 emissions targets• Electrification of the transport and heat sectors • New challenges for distribution networks due to generation

and increase in load• Voltage control• Powerflow management

Customer Led Network Revolution• Largest UK smart grid trial (£54m)• Large industrial collaborative partners

• Northern Powergrid• British Gas• EA Technology

• Socio-technical approach – Interdisciplinary research• Durham Activities

• Socio-technical trial design • Trial analysis and evaluation• Dissemination

Learning Outcomes• Learning Outcome 1 (LO1)

- Current, emerging and future customer characteristics• Learning Outcome 2 (LO2)

- Customer flexibility cost and value• Learning Outcome 3 (LO3)

- Network flexibility cost and value • Learning Outcome 4 (LO4)

LO3: Network Flexibility Trial Equipment

• Four test cells• Rural Network (Denwick)• Urban Network (Rise Carr)• PV Test Network (Maltby)• Heat pump (Hexham)

• Network Equipment• Energy Storage Systems (2.5MVA, 5MWh to 50kVA, 100kWh) • Demand Side Response (Residential, SME and I&C)• Integrated control of transformer and regulator tapchangers across

the voltage levels (66kV down to 400V)• Real Time Thermal Ratings (Cables, Transformers and Overhead Lines)• Integration is key, multiple active systems in collaboration

LO3: Network Trial requirements

• Ensure customers are not adversely affected• Enable model validation• Baseline required to evaluate existing performance of the system• Independently and in a control system• Network interventions with multiple functions (energy storage P/Q

powerflow/voltage control)• Local measurements/Global measurements• Interaction with other network interventions• Distributed/hierarchical control systems evaluation• Millions of possible combinations
