• A Fully Distributed Reactive Power Optimization and Control Method for Active Distribution Networks (2014, background): “The dc power flow approximation linearizes the constraints and makes the problem easier to solve [8], [9]; however, accuracy is not guaranteed because this may not be a good approximation for ADNs.”
