GridAPPS-D Field Bus Implementation

gridappsd-field-bus

A distributed field bus communication framework for the GridAPPS-D platform. Provides hierarchical agent-based communication across power grid field devices, enabling decentralized control and context management at the substation, feeder, switch area, and secondary area levels.

Features

• Message Bus Abstraction - Pluggable message bus architecture with support for STOMP, GridAPPS-D, and VOLTTRON connection types
• Distributed Agents - Hierarchical agent framework (SubstationAgent, FeederAgent, SwitchAreaAgent, SecondaryAreaAgent) for multi-level grid communication
• Context Management - Topology-aware context managers that provide neighborhood information to distributed agents via CIM-Graph
• Field Proxy Forwarding - Bridges field device buses to the operational technology (OT) bus when direct connections are unavailable
• Protocol Support - Extensible protocol transformers for IEEE 2030.5 and DNP3 field protocols

Installation

pip install gridappsd-field-bus

Requirements

• Python >= 3.10
• gridappsd-python
• cim-graph

CLI Commands

Start the field proxy forwarder:

start-field-bus-forwarder --username app_user --password 1234App

Start centralized context managers:

context_manager --feeder_id <feeder_mrid> --simulation_id <sim_id>
