ASSESSMENT OF FREQUENCY SUPPORT STRATEGY THROUGH TWO METHODS OF BATTERY STORAGE - DELOADING CONTROL

Abstract

Renewable energy including solar energy brings many benefits in reducing
the proportion of fossil energy that is gradually depleting, protecting resources
and the air environment. However, the high penetration of solar energy presents
challenges for the operation and stability of the system frequency because of the
instability due to weather factors as well as the non-participative operation.
participates in the inertial support of this energy source itself. There are many
frequency support methods applied, two of which are suggested: Using Battery
storage system and Deloading control. By creating more reserve power to
mobilize in time in case of imbalance of active power, thereby helping to
stabilize the frequency. The two methods met the frequency support capability
based on evaluation and simulation through Matlab/Simulink software.
