Power quality control in a stand-alone power system is a demanding task. For satisfactory operation, such systems are being augmented with fast-acting energy storage devices. In this article, a stand-alone wind–diesel system augmented with a small-rating superconducting magnetic energy storage system is considered for both reactive and real power balance. Suitable controllers are proposed which force the superconducting magnetic energy storage system to exchange both reactive and real power with the system under various perturbations. A simulation platform is developed in SimPower to virtually validate the system model and control design aspects. Superconducting magnetic energy storage system and its power electronic interface are represented by average value models and the various controller parameters are tuned using Genetic Algorithm. Simulation results show that both voltage and frequency of the system are improved.

Electric energy is the most convenient and clean energy sources, and it is used far and wide. While there are many problems of power quality which imperil greatly electronic loads. Modern times, high quality power supply is required by modern manufacturers, and a quick and efficient energy storage technology is now starved for in order to improve and solve the transitory power quality.As a new kind of energy storage component, super capacitors have fast response, high charge-discharge efficiency. This paper focuses on the application background that the super capacitor DC energy storage unit can improve the quality of electric energy, establish a mathematical model of the storage unit, analysis and design the control scheme of super capacitor DC storage energy system, to achieve rapid compensation of the instantaneous power of the system, effectively improving the power quality and stability of the system.
