A multi‐area design of under frequency load shedding schemes considering energy storage system

Abstract This paper presents a comprehensive under frequency load shedding (UFLS) model that can be implemented in multi‐area power system with real network characteristics. Conventional single‐area UFLS models operate on the basis of an equivalent center‐of‐inertia (COI) model, which ignores local dynamics response (SFR) and impacts location. Unlike single‐SFR is commonly utilized previous works, suggested or multi‐SFR plan this research has distinct benefit taking into account transfer across different electric areas. The proposed design incorporates flywheel energy storage (FESS) to support inertial alleviate more than 30% while improving nadir by 25%. In order investigate performance method high penetrations inertia‐free renewables, inertia reduced around 30%; therefore scheme assessed low scenario. multi‐stage formulated as mixed‐integer linear programming problem, optimal settings, including set‐points shedding, are then optimized. efficiency verified using IEEE‐118 Bus dynamic test system.
