PROJECT TITLE :

Risk-Based Management of Overloads Caused by Power Injection Uncertainties Using Power Flow Controlling Devices

ABSTRACT:

Increased penetration of renewable energy results in increased challenges for the transmission system operators (TSOs) to control their system in an exceedingly secure method. Through the limited means accessible to the TSOs to manage power flows in the system, reliability is jeopardized. Reliability should be managed differently, replacing this ways of reliability management which fails as uncertainty will increase. In this paper, a unique risk-based approach of system operation is proposed which will be useful for the TSOs to assess the confidence of system operation day-ahead, that's, the chance of the forecasted system to finish up in an insecure state is calculated. This paper only focuses on violation of power flow constraints within the system. It conjointly demonstrates the increase of this operation confidence using already put in power flow controlling devices. It is shown that these devices aid in enhancing confidence of system operation by shifting power flows to a more optimal one in the sunshine of generation uncertainty. The main emphasis is laid on preventive action. The proposed approach is demonstrated on check systems.
