Vanadium Redox Battery Energy Storage and Power Generation System Incorporating and Optimizing Diesel Engine Generators
U.S. Patent Number: 7,353,083
A power generation system includes a vanadium redox battery that interfaces with a control system to optimize performance and efficiency. The power generation system may include one or more wind turbine generators and one or more diesel fuel generators. The control system manages the vanadium redox battery’s absorption and power generation to control system stability and system frequency. The control system further manages the operation of the wind turbine generators and diesel fuel generators to control system stability and voltage.
Power Generation System Incorporating a Vanadium Redox Battery and a Direct Current Wind Turbine Generator
U.S. Patent Number: 7,265,456 B2
A power generation system includes a wind turbine generator and a vanadium redox battery to compensate for fluctuations in wind power. The wind turbine generator provides DC power that may be used to charge the vanadium redox battery. Generated DC power may also be used for power distribution and, if required, supplemented by DC power from the vanadium redox battery. The power generation system interfaces with a control system to optimize performance and efficiency.
Method for Retrofitting Wind Turbine Farms
U.S. Patent Number: 7,227,275 B2
A power generation system with a predetermined rating limit includes one or more wind turbine generators and a vanadium redox battery. The vanadium redox battery absorbs excess energy to ensure that the rating limit is not exceeded, provide system stability, and improve power generation availability. The power generation system may further include a control system to manage the vanadium redox battery’s absorption and power generation to control system stability and system frequency.
Telecommunication System Incorporating Vanadium Redox Battery Energy Storage System
U.S. Patent Number: 7,181,183 B1
A telecommunication system incorporates a vanadium redox battery energy storage system. The vanadium redox battery energy storage system receives and is charged by DC power. Upon power interruption, telecommunication equipment relies on the vanadium redox battery energy storage system to receive DC power. A charger/rectifier monitors received AC power to determine if an AC power interruption is occurring and initiates DC power transmission from the vanadium redox battery energy storage system to the telecommunication equipment.
System and Methods for a Self-Healing Grid Using Demand Side Management Techniques and Energy Storage
U.S. Patent Number: 7,184,903 B1
A self-healing power grid control system includes a power grid having a plurality of network islands with a plurality of linear and non-linear loads. A plurality of control sensors communicate with the power grid to monitor the electrical characteristics of the power grid. A plurality of controlled relays are in electrical communication with the plurality of non-linear loads. A battery energy storage system (ESS) is in electrical communication with a main power source and a network island. A first restoration controller is in electrical communication with the control sensors, the controlled relays, and with the battery ESS. The first restoration controller receives control signals from the control sensors, and in response to detecting an irregularity in the power grid, automatically actuates the battery ESS to stabilize power to the linear loads, and disconnects selected controlled relays to disconnect power to a calculated percentage of the non-linear loads.

Power System Stabilization System and Method Employing a Rechargeable Battery System
U.S. Patent Number: 6,563,234 B2
A power system stabilization system is provided between power generation equipment significantly fluctuating in output and a power system required to maintain a predetermined voltage. In the power system stabilization system, a voltage detection device and a current detection device detect voltage and current, respectively, of the power system and voltage and current thus detected are used to calculate a level of active power required and that of reactive power required which are referred to provide charging and discharging from a rechargeable battery to the power system via an A-D converter.
