A method for verifying that a power network model matches an electric power network providing electrical power to multiple assets positioned in multiple locations in a geographical area, the method comprising:
- accessing, by a validation device, the power network model, wherein the power network model is generated from asset data stored in a geographic information system database and describing assets and power stations of the electric power network;
- computing, by the validation server, a validation score for the power network model by performing operations comprising:
- (a) computing a connectivity score indicating connectivity errors in the power network model as compared to the electric power network, wherein computing the connectivity score comprises:
- (i) detecting connections among modeled nodes in the power network model and a modeled power source in the power network model,
- (ii) generating, in a non-transitory computer-readable medium, a graph data structure representing the modeled nodes and the connection,
- (iii) detecting, from the connections represented in the graph data structure, de-energized nodes in the power network model that lack connectivity to the modeled power source, and
- (iv) calculating the connectivity score as a function of a number of the nodes and a number of the de-energized nodes, wherein an increase in the number of the de-energized nodes causes the connectivity score to indicate increased connectivity errors,
- (b) computing an asset score indicating power-delivery attribute errors in the power network model with respect to power-consuming assets serviced by the electric power network, wherein computing the asset score comprises:
- (i) identifying modeled assets included in the power network model,
- (ii) determining that deficient assets, which are a subset of the modeled assets, have power-delivery attribute values indicating a power-delivery error, and
- (iii) calculating the asset score as a function of a number of the modeled assets and a number of the deficient assets, wherein an increase in the number of the deficient assets causes the asset score to indicate increased power-delivery errors,
- (c) computing a power-flow score indicating power-flow calculation errors in the power network model with respect to voltage ranges specified for the electric power network, and
- (d) calculating the validation score based on the connectivity score, the asset score, and the power-flow score;
- determining, by the validation server, that the validation score is below a threshold validation score;
- computing, by the validation server, an updated validation score subsequent to a modification in the power network model, wherein the modification changes one or more of (i) the connections in the power network model, (ii) the power-delivery attribute values in the power network model, and (iii) power-flow calculations in the power network model;
- and
- causing, by the validation server, a control system to identify and correct errors in the electric power network using the power network model with the modification, wherein the validation device outputs the power network model based on the updated validation score exceeding the threshold validation score.
