Energy-storage peak-shaving wind power generation charging-replacing stud

Abstract

The invention provides an energy-storage peak-shaving wind power generation charging-replacing stud. In 2011, the phenomenon of wind abandoning and electricity limiting is severe, no less than 584 wind power plants are 15% in average wind abandoning rate, and direct economic loss is close to 10 billion. Experts indicate that wind power is poor in stability and controllability, thereby being poor-quality energy for a power grid and bringing difficulty to smooth running of the power grid, so that wind power has to be abandoned. Consequently, in order to enable the wind power market to be bigger and stronger, a wind power development mode must be converted practically. The energy-storage peak-shaving wind power generation charging-replacing stud can consume wind power quite conveniently in situ to solve the problem of grid connection of the wind power, electric energy is generated through a windmill propeller [2] and a power generator [1] connected with the same, effect of peak shaving and energy storing in an electricity consumption trough is realized through a power transmission and energy storage peak-shaving conversion controller [3], an alternating-direct current converter [4] and a storage battery [6], and an electromobile is directly charged through a booster output charger [5] and a cord plug. The energy-storage peak-shaving wind power generation charging-replacing stud is huge in market space and is an optimal wind energy utilization device, and the objectives of effective utilization of wind energy and lowering of wind power cost are achieved.

Description

(1) Technical field [0001] The invention relates to an energy-storage peak-shaving wind power charging and replacing plug for on-site consumption of wind power, which is composed of a wind power generation system, an energy-storing peak-shaving system and a charging-swapping system. (two), background technology [0002] With the shortage of global conventional energy and the aggravation of environmental pollution, seeking to use pollution-free renewable energy has become the general trend of global energy development. The world is paying more and more attention to the development of alternative energy sources. Among various alternative energy sources, wind energy is the most mature, and its power generation costs are constantly decreasing. Wind energy is an abundant and clean natural energy, and the effective use of this renewable energy is of great significance. A wind generator is a common wind energy utilization device, which generally includes a windmill propeller blade...

Problems solved by technology

However, wind power still has the problem of being difficult to connect to the grid. It is a pity that a large part of wind power cannot be connected to the grid and is wasted in vain! On January 5, 2010, "People's Daily" reported that about half of the wind power generation capacity in Northeast China was idle

On June 22, 2012, "China Environment News" reported on the title "Where does the wind vane point to?" "Maximize the utilization ratio of wind power": wind power is the cleanest energy source, but in 2011, the phenomenon of abandoning wind power in my country was serious, As many as 584 wind farms have an average abandonment rate of 15%, and the direct economic loss is nearly 10 billion yuan

At present, the so-called environmentally friendly electric vehicles use secondary energy electricity, which is the electric energy obtained through multiple energy conversions of fossil fuels (coal → thermal energy → steam energy → mechanical energy → AC electric energy → chemical energy → direct current electric energy) and then For electric vehicles, the demand is large, and it is a waste of electric energy

This cannot achieve the real sense of environmental protection

As we all know, every conversion of energy needs to consume a certain proportion of energy. This kind of secondary and multiple energy conversion further reduces the effective utilization rate of energy, which is really too wasteful! Therefore, to make the wind power market bigger and stronger, it is necessary to effectively change the wind power development mode
