APPLICATION OF ADVANCED ENERGY STORAGE IN RENEWABLE ENERGY POWER GENERATION

ABSTRACT

This work to the introduction of the concept of generalized momentum power system, through the establishment of the flywheel energy storage system and super capacitor and generalized momentum of renewable energy power generation system model, the generalized momentum compensation control method is proposed. The flywheel energy storage device and super capacitor connected to the renewable energy power generation system of central point voltage, real-time bus voltage to test the voltage of the central point, flywheel angular velocity, computational power system equivalent inertia parameters and the instantaneous momentum flywheel energy storage devices. Calculate the momentum increment of the renewable energy system relative to the standard state; The angular velocity of the flywheel is adjusted so that the momentum increment of the flywheel storage device is equal to the momentum increment of the renewable energy generating system. This method will flywheel energy storage and super capacitor technique is applied to renewable energy power generation system can solve the energy state of renewable energy power generation system, real-time measurement and calculation as well as the energy storage system and energy exchange between the renewable energy generation systems control method.
