The present disclosure relates to systems and methods of simulating a power system using field data. For example, an embodiment may include a processor operatively coupled to a memory. The processor may receive a power system model representative of an actual power system. The processor may receive field data from the actual power system. The processor may initialize the power system model based on the field data to represent a state of the actual power system. The processor may simulate at least one scenario on the power system model. The processor may provide results of simulating the at least one scenario.

A communications network for communication between at least one power electronics element and at least one control unit is disclosed. According to one or more embodiments, the communications network can be described as a communications network having parts or portions thereof employing multi-hop and/or hybrid communication.

A single point to modify a behavior of intelligent electronic devices (IEDs) between active and testing modes is disclosed herein. The IED may include a variety of logical nodes, each with a behavior object related to the active or testing mode behavior of the IED. A single testing mode selection point of the IED is used to modify each of the logical nodes to change between active and testing modes. The testing mode selection point may be a logical input. The testing mode selection point may be a physical switch on the IED.

A smart plug may provide a smart-plug power monitoring signal that includes information about power consumption of devices connected to the smart plug. The smart-plug power monitoring signal may be used in conjunction with power monitoring signals from the electrical mains of the building for providing information about the operation of devices in the building. For example, the power monitoring signals may be used to (i) determine the main of the house that provides power to the smart plug, (ii) identify devices receiving power from the smart plug, (iii) improve the accuracy of identifying device state changes, and (iv) train mathematical models for identifying devices and device state changes.

Systems, methods and apparatus are disclosed for interfacing process controllers in a process automation system with one or more intelligent electrical devices (IEDs) of an electrical automation system to use process and electrical control space information to perform actions and make decisions regarding actions in a connected enterprise system to facilitate energy management goals as well as process control goals in view of electrical control space information and process control space information.

A microgrid according to an exemplary aspect of the present disclosure includes, among other things, a plurality of intelligent electronic devices configured to communicate directly with one another in a first language. Each of the intelligent electronic devices includes a controller and a gateway. The gateway is configured to convert incoming messages from the first language to a second language native to the controller. The first language is different than the second language. A method is also disclosed.

A process for detecting statistically significant changes in energy consumption patterns by monitoring for changes in the parameters to a parametric energy model. Two parametric models of energy consumption are created: the first being a model providing an initial base line of energy consumption, the second being a test model to be compared to the initial base model. Statistically significant changes are detected by using a difference score that compares the parameters of two models along with the uncertainties of each parameter to determine whether the differences in the parameters of each model indicate a statistically significant deviation in the energy consumption pattern.

A system for autonomous control in power systems is disclosed. In particular, a secure overlay communication model (SOCOM) is disclosed, the system including a combination of hardware and software for detecting power grid states, and determining appropriate actions for addressing detected states. The SOCOM is a logic-based system deployed onto computing devices such as field programmable gate arrays installed at bus controllers, Supervisory Control and Data Acquisition Systems (SCADAs), Intelligent Electronic Devices (IEDs), or other computing devices in power grid stations and substations. The logic-based nature of the SOCOM allows for seamless integration with preexisting power system equipment. In response to detecting various power grid faults such as line failures and over-current states, the system automatically rearranges power line configurations at the power stations and/or substations. The SOCOM further provides improvements relating to optimal power flow, cost-based power distribution, load management, voltage/volt-amp reactance (VAR) optimization, and self-healing.

The present disclosure relates to systems and methods of predicting voltages for various contingencies. For example, a monitoring system may include a processor that acquires at least one contingency of an electric power delivery system. The processor may acquire an expected control action based on the at least one contingency from controllers/IEDs. The processor may predict a voltage of at least one bus of the electric power delivery system by simulating the change in the state of the electric power delivery system caused by the expected control action. The processor may determine that the voltage of the at least one bus is predicted to violate one or more operational settings of the electric power delivery system if the at least one contingency were to occur. The processor may provide an indication that the voltage violates the one or more operational settings on a display of the electronic device.

An electrical power cord includes intelligent switching capability. An electrical power input receives electrical power from a power source, and selectively conveys that power to an electrical power output only when certain occupancy or power usage criteria are met. The electrical power output conveys electrical power to an electrical consumer when a switch disposed along the power cord is closed. The switch is actuated in response to a signal received from a sensor, such as an occupancy sensor or a power consumption sensor, and breaks continuity along the power cord when signals received from the sensor indicate that the occupancy or power usage criteria are not being met, which criteria may be customized for a particular application. The electrical power cord is operable to automatically reduce or substantially eliminate power consumption at its power output end.
