Simplified Voltage Sensitivity Based Curtailment Arrangement for Active Network Management

Distribution networks are moving away from a traditional fit and forget approach to an actively managed approach. Flexible distributed generation schemes are offered by distribution network operators (DNO) as an alternative to the costly reinforcement. Customers must be willing to reduce generation output to ensure the network is kept within operational limits. With DNOs transitioning to distributed system operators (DSOs), the design of market solutions to actively manage their networks is having greater importance. To improve the efficiency of how curtailment is done in an actively managed network, this paper proposes a simplified method to connect and manage devices based on voltage sensitivity estimation, which is computationally viable with considerable improved curtailment efficiency when compared with traditional schemes. Computational burden is shared amongst participating devices and Active Network Management. Thus, enabling the solution to be applied to a more realistic distribution network automation scheme, with less computational and communication burden.
