Problems solved by technology

However, both methods have limitations. Firstly, it only controls one aspect of source, network and load, and cannot carry out collaborative optimization control from an overall perspective; secondly, it does not distinguish the resources of the distribution network and does not consider the voltage level. , it is difficult to achieve co-optimization

Abstract

The invention provides a controllable load and clean energy power generation technology collaborative optimization control method. The controllable load and clean energy power generation technology collaborative control method is divided into a global operation decision-making system and an active load management system in a layered architecture mode. The global operation decision-making system isthe core of the whole system and comprises a global optimization layer, a collaborative control layer and a local control layer; and the active load management system adopts a layered form and is divided into a load optimization layer and a real-time response layer. According to the invention, a hierarchical collaborative control technology is adopted; characteristic complementation of controllable loads and a clean energy power generation technology is achieved through interaction of power grid loads, and overall collaborative scheduling of the controllable loads in an area is achieved, so that power fluctuation caused by an intermittent power source can be restrained, the new energy acceptance capacity of the whole network can be improved, and meanwhile a technical means is provided forvalley load shifting. The technical scheme is suitable for being applied as a controllable load and clean energy power generation technology collaborative optimization control method.

Description

technical field [0001] The invention relates to the technical field of power grid dispatching control, in particular to a collaborative optimization control method for controllable load and clean energy power generation technology. Background technique [0002] In a traditional power system, the power supply side is mainly composed of conventional power sources such as thermal power and hydropower, and the load side is mainly composed of uncontrollable conventional loads. The computer is transmitted from the power supply side to the load side through the power grid. Passive regulation by dispatch control system. With the emergence of new elements such as clean energy power generation technology, controllable load, and energy storage devices, the traditional dispatching operation mode can no longer meet the future power demand. The peak-to-valley difference and network loss during the operation of the power grid can promote the active participation of end users in the optima...
