Optimal Coordinated Operation of Distributed Static Series Compensators for Wide-area Network Congestion Relief

引用

Journal of Modern Power Systems and Clean Energy 2022年第5期10卷 1374-1384页

作者： Camilo Andres Ordonez M Antonio Gomez-Exposito Guillermo EVinasco M Jose mar.a Maza-ortega IEEE Smart Wires Union CityUSA Department of Electrical Engineering University of SevilleSevillaSpain Interconexion Electrica SA Intercolombia Sevilla Spain

Relieving network congestions is a critical goal for the safe and flexible operation of modern power systems, especially in the presence of intermittent renewables or distributed generation. This paper deals with the real-time coordinated operation of distributed static series compensators(DSSCs) to remove network congestions by suitable modifications of the branch reactance. Several objective functions are considered and discussed to minimize the number of the devices involved in the control actions, the total losses or the total reactive power exchanged, leading to a non-convex mixed-integer non-linear programming problem. Then, a heuristic methodology combining the solution of a regular NLP with k-means clustering algorithm is proposed to get rid of the binary variables, in an attempt to reduce the computational cost. The proposed coordinated operation strategy of the DSSCs is tested on several benchmark systems, providing feasible and sufficiently optimal solutions in a reasonable time frame for practical systems.
