Abstract:  ABSTRACT:  To increase the stability of power system with the increasing permeability of distributed generators, domestic and foreign scholars put forward virtual synchronous generator control strategy, which introduces the rotational inertia and damping characteristics of synchronous generator into traditional inverter control strategies to improve the friendliness of distributed generation. This paper proposes the power allocation method of the hybrid energy storage system with battery and ultracapacitor in virtual synchronous generator, and analyzes the setting of key parameters. Finally, this paper analyzes the power allocation effect of the hybrid energy storage system on DC-side under the conditions of constant load, step mutation and continuous change through Matlab/Simulink simulation model, which verifies the feasibility and effectiveness of the proposed power allocation scheme.

 

Key words:  KEYWORDS:  virtual synchronous generator, hybrid energy storage system, ultracapacitor, power allocation, control strategy
