Abstract

This paper presents a co-simulation platform (CSP) developed as a part of the "Microgrids, Infrastructure Resilience and Advanced Controls Launchpad (MIRACL)" project, hereafter called MIRACL-CSP, to allow simulation-based testing, demonstration, and evaluations of distributed wind under various grid operating conditions. MIRACL-CSP provides modular interactions among the power distribution system, distributed wind, and utility decision-making framework. A hierarchical engine for large-scale infrastructure co-simulations (HELICS) is used as the core engine of MIRACL-CSP to establish time and information coordination among the MIRACL-CSP modules. In this study, MIRACL-CSP performance is demonstrated using the IEEE 123-node test distribution grid modeled in GridLAB-D and the utility decision support application modeled in Python. The functionality of MIRACL-CSP is demonstrated through various grid operational scenarios in a microgrid and networked microgrid environment. A co-simulation study is described that demonstrated MIRACL-CSP capabilities for the microgrid operational scenario in the IEEE 123-node test system. MIRACL-CSP is a generic platform that facilitates distributed wind research for different test systems, applications, and valuation of distributed wind.
