Local voltage control in distribution networks using PI control of active and reactive power
Electric power systems research, 2022 —Overvoltage is becoming increasingly prevalent in distribution networks with high penetration of renewable distributed energy sources (DERs). Local control of converter-based resources is a flexible and scalable method to prevent this growing issue ...

Reactive power limits in distributed generators from generic capability curves [PDF]
2014 IEEE PES General Meeting | Conference & Exposition, 2014 This paper presents a generic trapezoid-type capability curve for any distributed generation technology. This curve is used to estimate the machine reactive power limits in terms of the actual active power and terminal voltage. The proposed simplification was tested on synchronous machines, doubly fed induction generators and full power converter ...

Power and limits of reactive agents [PDF]
Neurocomputing, 2002 In this paper I will show how reactive agents can solve relatively complex tasks without requiring any internal state and I will demonstrate that this is due to their ability to coordinate perception and action. By acting (i.e. by modifying their position with respect to the external environment and/or the external environment itself), agents partially

Optimal Distributed Feedback Voltage Control Under Limited Reactive Power
IEEE Transactions on Power Systems, 2020 In this paper, we propose a distributed voltage control in power distribution networks through reactive power compensation. The proposed control can (i) operate in a distributed fashion where each bus makes its decision based on local voltage measurements and communication with neighboring buses, (ii) always satisfy the reactive power capacity ...
