Abstract

The invention belongs to the technical field of power distribution network distributed voltage control, and discloses a power grid distributed voltage control distributed power supply optimization system. The power grid distributed voltage control distributed power supply optimization system comprises a data acquisition module, a user power consumption demand prediction module, a central control module, a distributed power supply access sensing module, a power distribution network load flow calculation module, a network loss determination module, a voltage stability analysis module and a distributed power supply acceptance capability calculation module. An electricity optimization control model building module; and a power supply optimization module. The method does not need a large amount of communication data, is simple and convenient in calculation, does not involve complex mathematical calculation, does not need the load distribution condition of a distribution network system, is high in calculation result precision, and can maintain the calculation result to be slightly greater than an actually accessed voltage value. A consistent optimistic evaluation result can be provided for the influence of the access of the distributed power supply controlled by the power grid on the voltage of the power distribution network, and the method has relatively high engineering practical value.

Description

technical field [0001] The invention belongs to the technical field of distributed voltage control of power distribution network, and in particular relates to a distributed power supply optimization system for distributed voltage control of power grid. Background technique [0002] At present, with the rapid development of my country's economy and society, the scale of large power grids and centralized power supply is rapidly expanding, and with this rapid development comes the issue of power grid security. The distributed power generation system has the characteristics of small footprint, short construction period, low voltage level, close to the load center, energy saving, and environmental protection. Therefore, distributed power generation can be used as a beneficial supplement to centralized power supply. [0003] The access of distributed power to the existing distribution system can improve energy utilization, improve the stability, reliability and economy of the powe...
