Ancillary Services in High-Renewable Power Systems: Comparing Market Design, Emerging Trends, and Future Challenges
Andreas Makrides, Andrey Churkin, Fei Teng +1
Rapid growth in renewable generation is changing power-system operation and increasing the importance of ancillary services for security and reliability. As inverter-based resource…
Exposing Barriers to Flexibility Aggregation in Unbalanced Distribution Networks
Andrey Churkin, Wangwei Kong, Pierluigi Mancarella +1
The increasing integration of distributed energy resources (DER) offers new opportunities for distribution system operators (DSO) to improve network operation through flexibility s…
Interpreting the Value of Flexibility in AC Security-Constrained Transmission Expansion Planning via a Cooperative Game Framework
Andrey Churkin, Wangwei Kong, Mohammad Iman Alizadeh +3
Security-constrained transmission expansion planning (SCTEP) is an inherently complex problem that requires simultaneously solving multiple contingency states of the system (usuall…
Impacts of Distribution Network Reconfiguration on Aggregated DER Flexibility
Andrey Churkin, Miguel Sanchez-Lopez, Mohammad Iman Alizadeh +3
The ongoing integration of controllable distributed energy resources (DER) makes distribution networks capable of aggregating flexible power and providing flexibility services at b…
Tracing, Ranking and Valuation of Aggregated DER Flexibility in Active Distribution Networks
Andrey Churkin, Wangwei Kong, Jose N. Melchor Gutierrez +2
The integration of distributed energy resources (DER) makes active distribution networks (ADNs) natural providers of flexibility services. However, the optimal operation of flexibl…
Assessing Active Distribution Network Flexibility: On the Effects of Nonlinearities and Nonconvexities
Andrey Churkin, Pierluigi Mancarella, Eduardo A. Martinez Cesena
A widespread approach to characterise the aggregated flexibility of active distribution networks (ADNs) is to estimate the boundary of the feasible network operating areas using co…
Assessing Distribution Network Flexibility via Reliability-based P-Q Area Segmentation
Andrey Churkin, Wangwei Kong, Jose N. Melchor Gutierrez +2
This paper proposes a framework to assess the flexibility of active distribution networks (ADNs) via P-Q area segmentation, considering the reliability of flexible units (FUs). A m…
