Abstract

This paper presents a statistical steady-state stability analysis for transmission system planning studies in order to identify operational issues inherent in the integration of offshore wind power plants. It includes normal and contingency operation. This study considers the integration of a 1000-MW offshore wind power plant into the FirstEnergy/PJM service territory in the U.S. Great Lakes region as a case study and uses a realistic computer model of the U.S. Eastern Interconnection, a 63,000-bus test system. The results show the utility of this statistical analysis tool and its effectiveness in identification of the operational impacts as a result of the integration of offshore wind power plant.

Highlights

Integration of offshore wind power plants into an existing power grid can cause operational challenges for the grid
This section investigates how variability of the offshore wind power plant can affect voltage and thermal stability of the FirstEnergy/PJM transmission system and assesses whether or not the stability of the system is threatened as a result of the offshore wind power plant integration
This study present a statistical approach for the steady-state stability analysis of large-scale power systems and addresses normal and contingency operation

Summary

Introduction

Integration of offshore wind power plants into an existing power grid can cause operational challenges for the grid. Steady-state analysis of electric power systems refers to the study of the system’s behavior while operating at an equilibrium point [1]. Given the uncertain and variable nature of wind, injecting electrical power generated from wind into a transmission system can escalate the complexities associated with the system’s operation and stability. This paper addresses this problem and introduces a statistical steady-state stability analysis tool that is practical for the planning studies associated with integration of offshore wind power plants into the transmission system
