Distributed photovoltaic group dispatching and group control system and method

The invention provides a distributed photovoltaic group dispatching and group control system and method. The system is characterized in that the system comprises a distributed photovoltaic DMS master station monitoring module, a DMS master station instruction issuing assembly, a DMS master station 10kV column switch and breaking switch information collection assembly, and a DMS distributed photovoltaic calculation control and operation assembly. According to the distributed photovoltaic group dispatching and group control system and method of the invention, the requirement of cooperative regulation and control of energy power generation and power grid power transmission is effectively met. Meanwhile, the invention provides a grid-source collaborative scheduling method for distributed photovoltaic output, reactive power and voltage support. Existing problems that a distributed photovoltaic power generation source in a 10kV line only provides active power and does not provide reactive power, and the active powe
