The invention discloses a flexible load autonomous controller capable of sensing power network voltage reduction. The controller comprises a power network voltage active sensing module, a microcontroller and a flexible load control execution module, wherein the flexible load control execution module comprises a solid-state relay module, a socket body and an infrared remote controller; and the microcontroller controls a power-on or power-off state of the socket body through the solid-state relay module. The invention furthermore discloses a control method of the flexible load autonomous controller capable of sensing the power network voltage reduction. The microcontroller monitors a power network voltage value in real time through the power network voltage active sensing module; and during the power network voltage reduction, the microcontroller can flexibly reduce household loads according to different power network voltage reduction degrees. A solid-state relay is adopted for performing adjustment, and a flexible reduction action can be finished within a time of 1ms, so that a power network dispatching center is effectively assisted in power network load adjustment in first time and stable power network voltage is maintained.
Description
technical field [0001] The invention relates to a flexible load autonomous controller that senses grid voltage drop, and also relates to a control method for the flexible load autonomous controller that senses grid voltage drop, belonging to the technical field of power system flexible load control. Background technique [0002] In recent years, with the increasing environmental pollution and the decrease of traditional coal energy, the proportion of distributed clean energy such as wind energy and solar energy is increasing. However, distributed clean energy has shortcomings such as poor controllability and uncertain intermittent time. Therefore, the State Grid continues to improve the power grid structure, transforming from a self-sufficient regional power grid to a large-scale receiving end power grid. This method can realize the dispatch of power resources across the country, so that power can be effectively allocated. But it also faces many new problems, such as: the su...
