Introduction  Base on the wind power, photovoltaic, small hydropower, coal-bed methane power generation and other intermittent energy with volatility and randomness, large-scale intermittent energy will bring great influence on the power grid′s safe and stable operation and control after connected to the power grid, and the traditional power grid operation control system can′t completely adapt to the operation control for large-scale intermittent power. In order to realize the operation control of the intermittent energy, it is necessary to study the intermittent energy control system.

  Method  In the paper, designed the system architecture, key application technology of multi-energy joint operation control system base on the characteristics of intermittent power, provided technology support for the control of the intermittent power.

  Result  Multi-energy joint operation control system has realized the intermittent power to participate in power grid operation control, and improved the ability to deal with the intermittent power fluctuation.

  Conclusion  The system has been applied in Guizhou power grid, and has been proved the feasibility of control of the intermittent power.
