A microgrid includes a plurality of distributed energy resources such as controllable distributed electric generators (104, 106, 108, 110, 112) and electrical energy storage devices (114). A method of controlling operation of the microgrid includes periodically updating a distributed energy resource schedule for the microgrid that includes on/off status of the controllable distributed electric generators (104, 106, 108, 110, 112) and charging/discharging status and rate of the electrical energy storage devices (114) and which satisfies a first control objective for a defined time window, based at least in part on a renewable energy generation and load forecast for the microgrid (200). The method further includes periodically determining power set points for the controllable distributed energy resources (104, 106, 108, 110, 112) which satisfy a second control objective for a present time interval within the defined time window, the second control objective being a function of at least the distributed energy resource schedule for the microgrid (210).
Converter stations (104) have real and reactive power set points initially determined as part of a main loadflow analysis routinely performed on the AC power system connected to the converter stations (104). Viable real and/or reactive power set points for the converter stations (104) can be identified by calculating real and/or reactive power set point candidates for the converter stations (104) before the main loadflow analysis is performed again on the AC power system. The power set point candidates are calculated based on information determined as part of a previous iteration of the main loadflow analysis on the AC power system. The power set point candidates which violate an operating constraint imposed on the AC power system are identified, and a region of valid power set points is defined for the converter stations (104) that excludes the power set point candidates which violate an operating constraint imposed on the AC power system.

The output parameter describes a condition of the industrial asset and can be defined using one or more variables. During deployment of the model within a deployment environment, respective variables of the model can be mapped to a data store where data associated with the variable is located. In this way, during development, a user can specify variables to be used within the model without specifying where to fetch and/or push data associated with the variable, for example. Further, the model can be executed within the deployment environment to assess the condition for a plurality of industrial assets.
Among other things, one or more techniques and/or systems are provided for developing a health profile of an industrial asset based upon data pertaining to such an industrial asset. At least some of the data is transformed into primary state indicators, respectively representative of the status or condition of an aspect of the industrial asset. Using the primary state indicators, one or more events that are likely to occur to the industrial asset are identified and a health profile is developed based upon such events. The health profile may describe maintenance actions that will reduce a likelihood of an event(s) occurring, may describe a business impact on an entity associated with the industrial asset if an event(s) occurs, and/or may describe a performance impact on the industrial asset if an event(s) occurs, for example.
Islanding events are detected using measurement information taken from several places in a network, e.g., from a system of intelligent electronic devices (lEDs ). In an example method of island detection, phase angle differences between local phase angles and remote phase angles in remote subnetworks are evaluated (850), and whether power is stable at the local and remote subnetworks is determined (860), using the local power data and the remote power data.
Among other things, one or more techniques and/or systems are provided for identifying event images captured during an event associated with power equipment, such as a maintenance action. An entity, such as a maintenance technician, is equipped with an image recorder and an audio recorder. In some embodiments, the image recorder and/or audio recorder are wearable, such as mounted to eyewear and/or headwear worn by the entity. Audio that is recorded by the audio recorder is processed to identify events (e.g., key actions in a maintenance procedure). Based upon the identification of an event from the audio, event images (e.g., images captured temporally proximate to when the event was identified in the audio) associated with the event are identified and stored in a library. In some embodiments, one or more of such event images are later displayed to entities via a heads-up display, for example.

TEMPERATURE COMPENSATED FIBER-OPTIC CURRENT SENSOR
In a fiber-optic current sensor, a 22.5° Faraday rotator,which is part of the sensing fiber coil,determines the working point of the sensor. The coil is operated with substantially linearly polarized light or incoherent substantially left and right circularly polarized light waves. In one arrangement, a polarization beam splitter generates two optical signals that vary in anti-phase with changing current. A signal processor determines the current from the two anti-phase signals. Appropriately detuned and oriented fiber-optic half-wave or quarter-wave retarders before the fiber coil are used to reduce or cancel the adverse effects of temperature and bend-induced birefringence on the measurement signal. Moreover, the temperature may be derived from the difference in the bias of the anti-phase signals and may be used to cancel temperature effects in the signal processor.
