INTEGRATED OPERATION OF AN ENERGY MICROGRID WITH ISLANDED ELECTRICITY NETWORK

1. INTEGRATED OPERATION OF AN ENERGY MICROGRID WITH ISLANDED ELECTRICITY NETWORK B. Awad, J. Wu, J. Ekanayake and N. Jenkins Centre for Integrated Renewable Energy Generation and Supply, Cardiff University

2. Background • The energy policy of the UK • Renewables, MicroGeneration, CHPs, and District heating • Community energy systems and Energy MicroGrids AWAD–UK–RIFS4–0344

3. Energy MicroGrid • An electricity MicroGrid • A District Heating System. • Interconnected at the CHP Unit • Both serve the same group of consumers. • Generation/demand balancing is a challenge AWAD–UK–RIFS4–0344

4. Operation of the Energy MicroGrid • Should heat and electricity networks of the Energy MicroGrid be operated as an integrated system or as two independent systems? • Study tool: The Integrated Optimal Power Flow AWAD–UK–RIFS4–0344

5. Case Study • 24 hours study period • Islanded electricity network • IOPF used to produce optimal schedules • Integrated operation minimises the need to shed loads and to curtail generation Demand shed Generation curtailed AWAD–UK–RIFS4–0344

6. Conclusion • Energy MicroGrids • Integrated vs. Non-Integrated Operation • Integrated Optimal Power Flow for Heat and Electricity • Advantages of the Integrated Operation AWAD–UK–RIFS4–0344
