目前光伏接入电网后以自由发电的形式向电网输送电能，光伏出力的不确定性和预测手段的局限性，将对传统的电网调度、运行和控制带来极大的挑战。首先介绍西藏电网考虑光伏接入的有功调度控制系统体系架构，并阐释光伏有功控制两层控制框架和控制数据流程。然后结合西藏地区电源结构，建立光伏资源优先接纳的优化调度模型，并进一步提出适应光伏接入的多源协调控制策略。文中提出的有功控制系统已在实际电网得到应用，通过算例验证所提方法的有效性。

As the photovoltaic(PV)power station transmits power to the grid in a free mode after its integration,the output uncertainty and prediction limitations of the PV power pose severe challenges to the dispatching,operation and control of the power system. This paper introduces the architecture of the active power control system considering PV integration and then describes the two-layer control framework and control flow of the Tibet power grid. Moreover,based on the power source structure in Tibet,the optimization dispatching model for PV power is proposed and the multisource coordinated control stra-tegy is proposed for PV power integration. The proposed control system has been applied and validated in a provincial grid.
