Demo

I have now created a demo which visualises an electricity network with a number of generators and loads. When the demo is run, a load increases on the network, which is then satisfied by a generator ramping up to compensate. However doing this overloads two of the lines on the network. It then attempts to coordinate generators so that the lines are no longer overloaded. The objective function in use is a combination of minimising  the sum of carbon emissions and minimising the change of generators output.

Java implementation of CPLEX

I have written some code in Java which uses CPLEX to solve the same problem that I specified in my last post. The reason for using Java and CPLEX to specify the problem is that an actual simulation can be conducted that uses multiple CPLEX models to demonstrate the centralised approach to generator coordination. The simulation scenario is as follows:

1. Network is balanced, all thermal limits are satisfied. Carbon emissions are minimised. One generator/Node is nominated to follow loads within the network.

2. Load at a substation increases/line failure

3. This causes nominated generator to balance the demand

4. However in doing so this overloads a line.

5. Run the CPLEX code to optimise the thermal constraints within the network and also reduce the distance between the new power output of a generator and its previous power output when the network was overloaded.

6. network solution is achieved, network is restored back to fully working order.

This benchmark will be used to test the centralised, and eventually, decentralised approach.
