Method for controlling distributed power resources of active power distribution networks

Abstract

The invention relates to a method for controlling distributed power resources of active power distribution networks. The method is characterized in that unified dispatching and partition controlling effects are realized by the method, and the method includes steps of (1), determining a power coordination control scheme for the power distribution networks; (2), determining power coordination control objectives of the power distribution networks; (3), judging whether a power coordination control target is a peak load shifting control objective or not; (4), implementing the peak load shifting control objective; (5), implementing a protocol load curve operation control objective. The control objectives include the protocol load curve operation control objective and the peak load shifting control objective. The method has the advantages that a resource coordination control mode for the active power distribution networks is provided by the method and conforms to principles of 'unified dispatching and hierarchical control' of the traditional power transmission-distribution networks, and the power coordination control scheme is provided for establishing a distributed power capacity management system and is suitable for regions, micro-grids and tie lines.

Description

technical field [0001] The invention relates to the field of distributed power supply, in particular to a resource control method for distributed power supply in an active distribution network. Background technique [0002] In order to save investment, reduce energy consumption, and improve the safety and flexibility of the power system, in developed countries such as Europe and the United States, the traditional centralized single power supply system characterized by large units, large power grids, and high voltage is gradually becoming a centralized large power grid system. The way of combining with distributed power system has changed. In my country's power system, more and more distributed power sources are connected to the power distribution network, and their proportion in the power supply composition is also getting higher and higher. Therefore, the traditional distribution network has certain resource adjustment capabilities and is called an active power system. dist...

Problems solved by technology

[0004] At present, the development of distributed power is lagging behind compared with developed countries in Europe and the United States. At present, demonstration projects of smart distribution networks have been constructed in Sino-Singapore Eco-City, Nanjing Distribution Network, Shanghai Chongming Island and other places, and distributed power access has been carried out. However, the research on key technologies including the operation, control and communication of distributed power distribution network is still in its infancy. great development potential
