Abstract

The power grid is transitioning to a more integrated and complex system with increasing flexible energy resources at the distribution level. Although such resources present a huge potential for enhancing the operational efficiency, improper coordination can cause operational issues impacting the stability of the gird and thereby necessitates comprehensive assessment with integrated bulk system operations. Bulk system operations, typically, rely on a series of complex market process coordinated over multiple time-horizon, and simulating such operations can be complicated with a high barrier to entry. This work presents wrapper-based interfaces, leveraging MATPOWER-MOST, that reduces the complexities for emulating wholesale market operations and minimize the barriers for evaluating impacts of coordination-designs. The wrapper comprises of several functions that encapsulates the complex formatting and coordination requirements between market processes, and organizes the co-simulation-based information exchange. The presented interfaces are implemented on an 8-bus test system representing the ERCOT ISO. Simulation results demonstrate the wrapper capabilities to model wholesale market operations and evaluates the impact of coordinating flexible resources, like demand and energy storage, through appropriate operational metrics.
