Problems solved by technology

There are still many disadvantages of manual control, such as long response time, unreasonable power distribution, large adjustment error rate, high labor cost, etc. The way of starting and stopping the inverter is easy to implement but the distribution is unreasonable, and the power generation capacity of all solar panels cannot be fully utilized. At the same time, it also poses a major threat to the safe and reliable operation of the power grid.

Abstract

The invention provides an active power control device and control method for a distributed photovoltaic power station. The control device comprises a communication management module, a command processing module, an AGC module, a data management module and an information displaying module. The data management module is in charge of storing all data information related to an active power control system and in charge of history base and real-time base management. The information displaying module is in charge of displaying the operation information of the active power control system. The AGC module carries out active power distribution on all inverters through the equal-margin distribution strategy according to the latest real-time information received at present, so that the active power of the current power station meets the requirement of power grid dispatching.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power station control, and in particular relates to a distributed photovoltaic power station active power rate control system. Background technique [0002] According to the requirements of the "Technical Regulations for Photovoltaic Power Plants Connected to the Grid", photovoltaic power plants should have the ability to adjust active power and be able to control their active power output according to the instructions of the grid dispatching department. In the traditional power generation industry, active power control is already very mature, but in the emerging photovoltaic field, especially distributed photovoltaic power plants still face many problems. Due to the randomness, intermittent and periodic characteristics of solar resources and the geographical dispersion of distributed photovoltaic power plants, the active power control of distributed photovoltaics is much more complicated and...
