Using scalable open source software for electric distribution network intelligence.Contact
Using international standard file formats and open source software, electric utilities can convert their network, spatial, meter and asset data into engineering and business intelligence.Presentation
The system can be broken down into the following steps.
Proprietary data formats are converted into published standard formats.
Meter readings are converted to Metered Services Consumption Report (MSCONS) or plain .CSV files.
Processing can be roughly separated into the following forms:
9code provides open source software (the Magic Sauce) to tie all these technologies together. The mandate is to craft performant, scalable components that flexibly convert data into useful information from which users can extract actionable intelligence. The individual components are bundled into the following deliverable assemblies.
The CIMReader comfortably ingests gigabytes of electric network model data in CIM format and exposes it as Spark RDD structures. This is used to initialize a Spark environment for use either interactively in an ad-hoc analysis or as the first step in a programatic batch computation. The features are:
CIMSpace is a browser based client-side visualization and editing tool suitable for electric distribution networks up to a few hundred megabytes in size in CIM format. The features are:
The ShortCircuit assembly provides utility operators with various metrics for each customer (EnergyConsumer) connection. The process uses both static analysis and load-flow analysis and hence is suitable for both radial and mesh networks. It generates a SQLite database for use in downstream applications. Included metrics are:
The Einspeiseleistung assembly provides an estimate of the maximum feed-in power for new photo-voltaic installations at each customer location. The process uses static and load-flow analysis to find the limiting factor (voltage rise, cable current, transformer rating) and hence the maximum installable power at each customer location - assuming no network reinforcement. It generates a SQLite database for use in downstream applications.
The Simulation assembly is the mechanism to convert customer meter data into network values (currents, voltages, losses, power etc.). Each transformer service area is separately extracted and simulated using GridLAB-D using measurement values (e.g. 15 minute intervals) for each customer location. All source and simulated data is contained in a Cassandra database which can be accessed by downstream applications. In addition to raw simulated data, aggregations (min, max, average) over hourly, 3 hour and daily periods are computed. Various summary metrics are calculated for each element and the transformer area as a whole, such as:
CIMApplication is a J2EE server based user interface to all of the above functionality as well as providing a RESTful programmatic interface for consumption by other web services.
Running with the Spark/Cassandra cluster, it provides a graphical user interface to launch and view the results of analysis and simulation with the following functionality.
