Abstract

In this paper, a collaborative control scheme is proposed to improve the stability of the microgrid with intermittent renewable energy sources. Different from other cooperative control schemes targeting mostly on regulating the generation side, the proposed operating scheme utilizes all controllable resources in the microgrid, including renewable energy sources (RESs), storage devices, and controllable loads. A modified maximum power point tracking (MPPT) scheme is proposed for RESs in limiting its power output when frequency surges over its upper limit. The adaptive/smart load enabled by the electric spring (ES) reduces the power demand when the frequency falls below the lower limit. Both operating schemes for RES and adaptive/smart load can be activated when the storage system fails to respond to disturbances. The proposed collaborative scheme can be enacted in an instantaneous manner and is easy to implement by simply modifying the control of RES and adaptive/smart load. Simulation results have confirmed that the proposed scheme is efficient in reducing the frequency oscillation in a microgrid.
