In this paper, a fast load shedding remedial action scheme (RAS) is developed considering generation pattern of local wind farms using wide area monitoring framework. In the proposed RAS, the shedding candidates are selected and prioritized based on load types and their impacts on the voltage profile and transient performance of the system. The dynamics of wind farms are also included in the shedding requirements and formulas by defining effectiveness indices which are calculated based on the contribution of each generator to the dynamic performance of the system. This allows secure operation of the system after major contingencies while impacted customers are minimized. The proposed methodology, shedding formulas, and corresponding requirements are verified for the BC Hydro system using the PSS/E dynamic simulation package. [ABSTRACT FROM AUTHOR]

Abstract: This paper presents a new soft switching inverter with DC-link switch and one auxiliary switch. The important feature of this topology is that the switches voltage stress is lower than that of other quasi-parallel resonant DC-link inverters. All diodes and switches are turned on and off under soft switching conditions. Auxiliary switch is turned on and off under zero current switching conditions, and the DC-link switch is turned on under zero voltage zero current switching condition and turned off under zero voltage switching condition. The proposed converter is analyzed and its operating modes are explained in details. The presented experimental results of a prototype converter confirm the theoretical analysis.
