UTILIZING A LOAD FOR OPTIMIZING ENERGY STORAGE SIZE AND OPERATION IN POWER SYSTEMS REGULATION APPLICATIONS

摘要

An energy storage system that delivers electrical energy to and absorbs electrical energy from a power grid (304) comprises a storage bank (308) configured to store electrical energy received from the power grid (304) through a conversion unit (302), and to deliver stored electrical energy through the conversion unit (302). The energy storage bank (308) may be associated with a parameter. The energy storage system may further include a load (316) configured to dissipate electrical energy received from the power grid (304) through a load gate (312), and a control unit (310) operatively coupled to the conversion unit (302) and the load gate (312). The control unit (310) may be configured to control electrical energy flowing from the power grid (304) to the energy storage bank (308) and to the load (316), and electrical energy flowing from the energy storage bank (308) to the power grid (304), as a function of a signal from the power grid (304) and the parameter associated with the energy storage bank (308).
