Abstract

The invention discloses a distributed photovoltaic control system and control method based on multiple time scales and multiple spaces. According to load prediction and power generation prediction in a dispatching cycle, a power control strategy in a dispatching cycle in the future is formulated, so that a power generation dispatching plan is formed; in combination with short-period power generation prediction and short-term load prediction, the power generation dispatching plan is adjusted, so that a real-time power generation dispatching plan is obtained; according to the running condition of distributed photovoltaic equipment in each sub-area, the real-time power generation dispatching plan in the sub-area is obtained; and a command of the power generation dispatching plan is issuedto a photovoltaic controller to control the distributed photovoltaic equipment. According to the distributed photovoltaic control system and method disclosed by the invention, partitioned management is performed on distributed photovoltaic equipment accessed to a power grid under a condition that the power supply reliability is ensured; and the distributed photovoltaic power generation stability and the energy utilization rate are effectively increased.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a distributed photovoltaic control system and control method based on multiple time scales and multiple spaces. Background technique [0002] With the large-scale application of distributed power, the proportion of random, fluctuating and intermittent distributed energy in my country's power grid in the future, especially distributed photovoltaics, will become larger and larger, and will even become an indispensable part of the power grid. . A large number of distributed power generation is connected to the distribution network, and the large amount is scattered, and it is difficult for the power grid to regulate it, which will have many impacts on the safe, reliable, stable operation and control of the distribution network. [0003] At present, many scholars have conducted research on the control methods of distributed photovoltaics. The existing photovoltaic control methods are based...
