The Kent Active System Management project aims to trial new Contingency Analysis software to demonstrate improved operation and planning of the East Kent 132 kV distribution network. The project is expected to demonstrate that the network can be run closer to its design limits, releasing network capacity and deferring the need for significant customer-funded reinforcement. It will also reduce the amount of renewable electricity output that needs to be curtailed during essential maintenance or equipment faults.
The significant increase in uptake of renewable energy in recent years has placed electricity networks under greater pressure. This export of power onto the electricity is the most extreme form of the network operating in the opposite way to which it was originally designed, where sections of the network are not only supplying their own demand, but also exporting the surplus onto the transmission system.
There is no longer a simple ‘day of highest winter demand' and 'day of lowest summer demand', and the presence of multiple interconnectors and Grid Supply Points create a number of extreme scenarios that need to be analysed. This is therefore placing a greater requirement to monitor all contingencies on the electricity network.
