Value of thermostatic loads in future low-carbon Great Britain system [PDF]

, 2016
This paper quantifies the value of a large population of heterogeneous thermostatically controlled loads (TCLs). The TCL dynamics are regulated by means of an advanced demand side response model (DSRM).

Inertia Support Strategy for Wind Turbine Based on Switched Operating Points With Equivalent Time Constant

IEEE Access
The wind Turbine adopts Virtual Synchronous Generator (VSG) control to support grid frequency by releasing their energy reserve. However, the interaction between the maximum power point tracking (MPPT) control and VSG control will weaken their inertia ...

Fuzzy control based virtual synchronous generator for self-adaptative control in hybrid microgrid

Energy Reports, 2022
Maintaining the stability of low-inertia microgrid becomes a key challenge in the presence of high penetration of renewable energy sources. However, in such systems, the virtual inertia values are often fixed constants, and the choice of their values ...

A classification of structural inertia: Variations in structural response [PDF]

Asia Pacific Journal of Management, 2018
Structurally inert firms suffer elevated failure risks in the face of environmental change because inertia makes it difficult to keep pace with the speed of such change. Traditionally, this ecology theory based outlook focuses on the risks of mortality, treating the make-up of an organization’s architecture as uniform and thus relatively ...
