AB - Thepower transfer capability of existing transmission networkscan be enhanced through the use of automated system protection schemes (SPS), which rapidly respond to disturbances on the networkto keep the system’s variables within operational bounds. However, reliance on such schemes may expose the network to large impacts –including blackouts –if the SPS does not respond as designed, so the deployment of SPS should balancerisks and benefits.This paper formulates a risk-based cost-benefit framework that allows the operator to strike an optimal balance between constraint costs and risks of demand curtailment due to malfunctioning SPS. It is applied to a simple 4-bus power system inspired by the GB network, for which an exact optimisation problem can be formulated.A component-based dependability model is developed for the SPS to determine its failure modes and associated probabilities. The resulting cost-minimisation problem is solved for a range of operating conditions and SPSreliability levels. The results consistently show cost savings from the use of an SPS, even ifit is highly unreliable, when a hedging strategy may be used. The optimal solution is highly sensitive to the problem parameters, but it is demonstratedthat optimal operational strategies are associated with particular SPS outcomes.This finding may be used as empirical guidance to develop operational strategies for complex networks with unreliable SPS.
