Innovative control architecture

Proper selection of control techniques and settings is essential to ensure microgrid stability, and performance requirements and standards should be considered. Flexibility in control architecture design is important to avoid complexity and instability. Researchers are exploring solutions such as droop control and grid-forming inverter-based DERs to address these challenges. The objective of this study is to enhance the control architecture of microgrids by incorporating negative sequence control strategies. The proposed approach could potentially contribute to the widespread application and functionality of renewable energy microgrids.

24 Network and grid impact of VPPs

1. Network impact assessment: emulate the behaviour of VPP under different network conditions and comparing them to non-VPP cases

2. Dynamic local network operating envelopes: investigate the impact of dynamic local network operating envelopes for DER on the ability of VPPs to provide network and system services

3. Reliability analysis: Analyse the reliability of services provided by VPPs, and identify the factors that impact reliability

Optimal siting and sizing of microgrids and community batteries

1. A thorough study will be conducted to identify the most critical economic, social and technical factors influencing the best location for community batteries and various types of microgrids.

2. Conducting interactive surveys among different stakeholders will help determine the key sizing and siting factors.

3. An accurate decision-making tool will be developed to find the optimum location and scale of microgrids and community batteries.
