Research on the Automatic Electricity Use Restricting Load-shedding

The Electricity Use Restricting Load-shedding (EURLS) is a method to deal with the frequency decline caused by the power shortage or the accident of the power system. At present, the EURLS is implemented manually. This paper proposes an Automatic Electricity Use Restricting Load-shedding (AEURLS) to solve the problems of the manual EURLS. The AEURLS uses the design methods of the UFLS for reference. This paper first analyses the differences between the AEURLS and the UFLS, and then proposes the design principles of the AEURLS. Finally, this paper proposes three schemes for the Northeast Power Network. The simulation results prove that the AEURLS could solve the problems of the manual EURLS and it could be a theoretical reference for the practical use.
