Method for treating voltage and line loss problems of rural transformer area

Abstract

The invention relates to the field of power distribution network planning, in particular to a rural area voltage and line loss problem treatment method, which comprises the following steps: constructing an operation layer constraint condition and an objective function, constructing a planning layer constraint condition and an objective function, associating an operation layer and a planning layer, and solving operation. According to the method, a set of planning layer and optimization layer joint optimization model is constructed, network topology, line specifications and the like are used as static parameter input, a photovoltaic-load power generation scene reduced by an AP clustering algorithm is used as dynamic parameter input, active and reactive power resources such as energy storage, a static var generator and a photovoltaic power supply are comprehensively called, and the optimal power generation efficiency is improved. A planning layer and an operation layer are integrally associated to synchronously solve an equipment planning layer locating and sizing scheme and an operation layer optimization control strategy, and simulation is carried out on an actual engineering node example to verify the universality and rationality of a model.

Description

technical field [0001] The invention relates to the field of distribution network planning, in particular to a treatment method for voltage and line loss problems in rural station areas. Background technique [0002] In view of the voltage and line loss problems in rural areas, taking into account factors such as poor geographical location of rural distribution networks and backward infrastructure facilities, traditional methods such as adding substations and line reconstruction are difficult to implement due to factors such as terrain constraints and difficult construction. [0003] Under the current situation, it is feasible to use the existing resources such as the remaining reactive capacity of the inverter of the photovoltaic power generation system, as well as easy-to-deploy plug-and-play devices such as distributed energy storage and static var generators to participate in the governance of voltage and line loss problems. It is more reasonable to consider sex and econ...
