Systems and methods for demonstrating power control system (PCS) operating sequences provide a model builder and a sequence builder. The PCS model builder allows a user to build a graphical model of a PCS using drag-and-drop objects representing PCS components, such as generators, circuit breakers, transfer switches, and the like. The PCS sequence builder allows the user to enter plain language commands that represent operations performed by the model objects. The model builder then graphically animates the model according to the plain language commands. Animation may include changing an image color, shape, configuration, position, orientation, or size for the model objects. This allows any user to graphically demonstrate how a PCS would work before resources are invested toward developing the PCS.

The present disclosure provides a method for planning a distribution network with reliability constraints based on a feeder corridor, including determining installation states of respective elements in the distribution network; determining an objective function, the objective function being an objective function of minimizing a total investment cost of the distribution network; obtaining fault-isolation-and-load-transfer time and fault recovery time in a case where the feeder segment of each feeder line that is contained in each feeder corridor fails; determining constraint conditions including reliability constraints; building a distribution network planning model according to the objective function and the constraints; and solving the distribution network planning model built to obtain optimal solutions as planning states and reliability indexes to plan the distribution network.

Disclosed is a method for identifying fragile lines in power grid based on electrical betweenness, which comprises the following steps: constructing the power grid into a network diagram, sequentially removing lines in the network diagram, and sorting the electrical betweenness of each line from large to small; constructing a nonlinear model of complex network cascade failure considering overload and weighted edges, and respectively performing two ways of removing lines for sorted electrical betweenness, namely sequentially removing preset proportion lines and sequentially removing all lines until no new lines are removed in the network diagram; obtaining a change of generator-load power before and after each line removal, and evaluating a severity of power grid failure based on the change of generator-load power, thus completing an identification of power grid fragile lines.

A transient stability assessment method for an electric power system is disclosed. Transient stability tags and steady-state data of the electric power system before a failure occurs are collected from transient stability simulation data. Data sets under different predetermined failures are obtained based on a statistical result of the transient stability tags and a maximum-minimum method. A similarity evaluation index between different predetermined failures is constructed based on a Jaccard distance and a Hausdorff distance. Different predetermined failures are clustered based on a clustering algorithm. A parameters-shared siamese neural network is trained for different predetermined failures in each cluster to obtain a multi-task siamese neural network for the transient stability assessment. Transient stability assessment results of the electric power system under all the predetermined failures are obtained based on the statistical result of the transient stability tags and the multi-task siamese neural network for the transient stability assessment.

Tools and techniques are described to attach a device to a controller, whereby the controller analyzes the device inputs, looks up information about the device in a database, and then determines which inputs on the device match the defined device inputs. It then may translate information received from the device into an intermediate language. It may also use the information received from the device, the location of the device, and information about the device to create a digital twin of the device.

The method includes: identifying a coordinate of each memory macro cell in a power domain to be processed; determining a coordinate of a first area, a coordinate of each second area, and a coordinate of each third area according to the coordinate of the each memory macro cell; determining a first metal wire arrangement parameter in the first area according to a design requirement, determining a second metal wire arrangement parameter in each second area according to the coordinate of each second area, determining a third metal wire arrangement parameter in each third area according to the coordinate of each third area; performing a power supply network arrangement on the first area, each second area, and each third area according to the coordinate of the first area, the coordinate of each second area, the coordinate of each third area, and the corresponding first metal wire arrangement parameter, second metal wire arrangement parameter, and third metal wire arrangement parameter.

A controller is described with an adjacent electronic display which allows users to input building plans, and to design where devices (e.g., equipment and sensors) are to go. The controller has access to databases of the devices including wiring diagrams and protocols, such that the controller can automatically create a wiring diagram that can be used to wire the building and the controller. The adjacent display can be moved to show controller wiring, while the display shows a wiring diagram which describes a diagram of the controller wiring including devices that are connected, and wiring information about the devices.

Risk element information indicating risk elements is acquired. An asset capable of becoming a fault due to a risk element indicated in the risk element information, and a fault probability that the asset becomes the fault are specified based on static configuration information. A risk model in which the asset capable of becoming the fault and the fault probability are associated is generated in advance. In response to a designated input, an one asset to be evaluated is specified as an evaluation target asset, based on the designated input. A risk model related to the evaluation target asset is specified. A risk evaluation value being an index indicating a risk of the evaluation target asset is calculated based on the fault probability of the evaluation target asset and the static configuration information. The risk evaluation value of the evaluation target asset is associated with the asset of the risk model.
