SmartGrid: Load Balancing of Power Distribution Systems

Disclosed is a method for load balancing of power distribution systems.

Power distribution systems refer to the electricity network that connects to homes and business. Figure 1 shows many of its components which is a large and complex system. Majority of losses and outages happen in the distribution system. Being able to efficiently analyze the behavior is a big plus. In a power distribution network having multiple sub-networks connected with switches and wires, the disclosed method uses these switches/wires to balance load across the various components.

Figure 1

Transformers are basic and costly elements of power distribution networks. As shown in Figure 2, the life time of transformer depends on "stress" level, i.e. level of power transferred relative to rating. In order to maximize lifetime, its desirable to operate components at the minimum usage level possible. With multiple components, its desirable to have them all at the same percentage usage level.

Figure 2

As shown in Figure 3, the network has multiple sub-networks, connected with switches and extra wires in order to provide redundancy in the case of outages.
