Abstract:
Voltage balancing and extracted output power circuit topologies use maximum power point and maximum power point tracking to provide voltage balancing and voltage and current adjustment to optimize extracted output power for corresponding DC voltage source strings (120a, 130a). The topologies used to control power generation include one or more voltage balancing circuits and/or power system optimizer circuits (102a) to reduce decreased power utilization and enable independent operating voltages of DC voltage source strings (120a, 130a) to provide voltage balancing and to deliver a maximum power independent of the voltage and current of other DC voltage source strings (120a, 130a). The current flowing in each DC voltage source string is controlled by the duty ratio of the corresponding switch (101a, 108a). The circuit topologies can include a plurality of voltage balancing/power system optimizer circuits (102a).

A plan is generated in the system for optimized energy utilization at least on the basis of the energy amount that is stored in the mobile energy source and based on the energy consumption. Then, the energy flow between the mobile energy source connected to the docking station and the energy consumers is regulated based on the generated plan. The plan is generated and the energy flow is regulated by said agents.
