An Open Source Representation for the NYS Electric Grid to Support Power Grid and Market Transition Studies

M. Vivienne Liu, Bo Yuan, Zongjie Wang, Jeffrey A. Sward, K. Max Zhang, C. Lindsay Anderson

TL;DR

An overview of the current NYS power grid is presented and an open-source baseline model is developed, validated with real data for power flow and Locational Marginal Prices, demonstrating the feasibility, functionality, and consistency of the model.

Abstract

Under the increasing need to decarbonize energy systems, there is coupled acceleration in connection of distributed and intermittent renewable resources in power grids. To support this transition, researchers and other stakeholders are embarking on detailed studies and analyses of the evolution of this complex system, which require a validated representation of the essential characteristics of the power grid that is accurate for a specific region of interest. For example, the Climate Leadership and Community Protection Act (CLCPA) in New York State (NYS) sets ambitious targets for the transformation of the energy system, opening many interesting research and analysis questions. To provide a platform for these analyses, this paper presents an overview of the current NYS power grid and develops an open-source (https://github.com/AndersonEnergyLab-Cornell/NYgrid) baseline model using publicly available data. The proposed model is validated with real data for power flow and Locational Marginal Prices (LMPs), demonstrating the feasibility, functionality, and consistency of the model. The model is easily adjustable and customizable for various analyses of future configurations and scenarios that require spatiotemporal information about the NYS power grid with data access to all the available historical data and serves as a practical system for general methods and algorithms testing.
