Application And Research Of Energy Storage Technology In Power System

Energy storage technology is becoming more mature and its role is also growing in power systems. The energy storage device of power system can absorb excess energy and release it in the case of power shortage, contribute to achieving the balance of active and load demand.In this article, firstly, we discuss the basic principles of energy storage devices. It mainly involves batteries, super capacitors, superconducting magnetic energy storage device and pumped storage power station. Insight into the operating characteristics and mathematical model of each storage means. Then the paper studies the large-scale energy storage components in the power system. It studies the pumped storage units in case of emergency and how to use the principle of controlled conditions to convert to maintain stable operation of the power system, it buring up control measuresBased on the optimal control theory, it buring up control measures, using simulation software PSASP proved that pumped storage plant conditions to convert the control strategy is correct. Finally, based on double-fed wind turbines proposed Hamiltonian of DFIG-ESS (energy storage system) coordinated control strategy. Design and build a control system based on MSP430 MCU.
