Abstract: An electrical system for controlling a wind turbine is provided. The electrical system includes a first resistive element, a storage element and a controller. The first resistive element and the storage element are coupled to a DC link of the wind turbine. The controller is used for switching between the first resistive element and the storage element in response to a grid side fault condition to minimize mechanical loads induced by the grid side fault condition.

Abstract: An energy management system may include a plurality of energy resource systems for exchanging electric energy therebetween. According to some embodiments, each energy resource system includes a renewable energy resource to generate electric power and a power converter to convert the electric power from one form to another form. Each energy resource system may further include a local controller having a unique identification for the energy management system to control the operation of the power converter. A cloud controller may communicate with the local controller to exchange information over a communications network. The cloud controller might, for example, establish a secure connection with the local controller after verification of the unique identification and maintain at least one database to securely store information relating to energy exchanged between the plurality of energy resource systems in the form of a virtual renewable energy currency.

Abstract: A system may include an energy reservoir controller associated with a microgrid's energy reservoir adapted to store energy (e.g., a battery to store electrical energy). A computer processor of the energy reservoir controller may receive indications of digital currency tokens from a token creation platform. At least some of the digital currency tokens may be placed into an available energy container based on an amount of energy stored in the energy reservoir. A consumer within the microgrid may submit a transaction request for energy, and it may be arranged for an amount of energy to be transferred from the energy reservoir to the consumer. Based on the amount of energy transferred to the consumer, a number of digital currency tokens may be moved from the available energy container into a used energy container. Information about the transaction request may then be recorded via a secure, distributed transaction ledger.

Abstract: A yaw backup system is provided. The yaw backup system includes an energy storage medium for storing auxiliary power. The yaw backup system also includes a yaw controller for coordinating delivery of power from the energy storage medium to a yaw motor for controlling a yaw angle of a wind turbine during grid loss conditions. The yaw controller executes the steps of receiving wind direction signals over time from a sensor, altering a tolerance level of a wind turbine based on changes in the wind direction signals over time and controlling delivery of power to the yaw motor from the auxiliary power of the energy storage medium based on the tolerance level to control the yaw angle for reducing a load on the wind turbine induced by wind.
