Optimal Operation for the IEEE 33 Bus Benchmark Test System With Energy Storage

Abstract

In this work we address the optimal operation for an active distribution network that is being used as a benchmark test system. The optimal operation of the active distribution network is divided into two different optimization problems: the Unit Commitment and the Economic Dispatch. The Unit Commitment problem determines the start-up and shut-down schedule of all production units to supply the electric demand minimizing the total operating cost. Then, once the commitment of the generating units is decided, the Economic Dispatch determines, for each hour of the planning horizon, the actual power output of each of the committed generating units necessary to supply the demand and comply with the limits imposed by the transmission network. The optimal operation problem here presented is utilized to analyze two configurations: the first does not include energy storage while the second includes energy storage in two nodes. The results reveal the advantage of using energy storage. As future work, further research will be conducted to include the problem of determining the optimal location and size of storage units.
