The multi-dimensional nine-area optimal control strategy analysis method based the power distribution network system can realize comprehensive analysis and regulation of the power distribution network, can improve the stability of the system and the power supply quality of power consumers, and also can improve the grid voltage quality, reduce the network loss and reduce the labor intensity of dispatchers.

Description

technical field [0001] The invention belongs to the technical field of electric power system distribution network, and in particular relates to an analysis method based on multi-dimensional nine-zone optimal control strategy of distribution network system. Specifically, the reactive power compensation control device of the distribution network system is applied to the reactive power control of the distribution network system. Fully consider the peak and valley maximum values ​​of the actual load operation curve, and the time division of each load segment will change due to factors such as seasonality, holidays and working day differences, and synchronize the time segment setting with the change of the load segment. Background technique [0002] At present, the network loss of distribution network is relatively high, and AVC system is rarely configured, especially on 10kV lines, voltage and reactive power control is still dominated by manual regulation, which increases the la...

Problems solved by technology

At present, there are still widespread unqualified voltage phenomena in my country's distribution network due to uneven distribution of network structure, power supply radius, and power flow.

Especially in rural power grids, due to the lack of power points, long power supply radius, and large changes in load with seasons and time, the phenomenon of substandard voltage at the user's receiving end and large line loss is particularly prominent, resulting in the end-user electrical equipment at the end of the line during the peak load period. Unable to start normally, it is urgent to improve the voltage quality
