The application of energy storage technology in high penetration renewable energy systems are reviewed in this paper. Firstly, the characteristics of power system with high penetration renewable energy are analyzed. Secondly, the research direction and research status of domestic and international energy storage technology in high penetration renewable energy system are introduced. Then the application...
Due to the unbalance condition, the voltage of microgrid would be deteriorated. In this paper, a unify unbalance compensation strategy is proposed to suppress the unbalanced voltage and the voltage variation for islanded microgrid with unbalanced condition. Comparing to the traditional compensation strategy, where only negative sequence components of voltage are suppressed, in the proposed scheme,...
An intermittent power of renewable sources such as wind turbine and photovoltaic system can damage power quality and operation efficiency of generator. Specially, in case of standalone microgrid such as island power system, this intermittent characteristic of renewable resource can lead to severe problems, such as frequency oscillation and power fluctuation. This frequency oscillation and power fluctuation...
As a promising renewable resource, wind power is highly expected to contribute a significant part of generation in power systems in the future, but this also brings new integration related power quality issues due to its unconventional characteristics. To solve frequency fluctuating problems of wind power integration, this paper proposes an idea that it is possible and reasonable to use HVDC lines...
