Method for efficiently emerging marsh gas power generation into user power utilization network

Abstract

The invention provides a method for efficiently emerging marsh gas power generation into a user power utilization network. The method is characterized by comprising the following steps of: leading out two input ends from a utility power grid, wherein one input end is connected with a user power utilization network through a first switch, and the other input end is connected with the input end of a parallel controller through a second switch; connecting at least one marsh gas power generation device to the input end of the parallel controller; and adjusting the output voltage of the marsh gas power generation device to make the output voltage of the power generation device higher than a utility power voltage. One or more marsh gas power generation devices are connected in parallel with theutility power, mainly adopt the utility power and are assisted by marsh gas power generation. The electrical energy provided by the marsh gas power generation device is first utilized without affecting user power utilization. The method realizes the effect of efficiently merging the marsh gas power generation into the user power utilization network.

Description

technical field [0001] The invention relates to a method for using biogas to generate electricity and integrate it into a user's electricity network. Background technique [0002] As the world's conventional energy sources are increasingly depleted and energy consumption is increasing, mankind is about to or has already faced a crisis of energy shortage. On the other hand, a large number of small-scale renewable energies have not been effectively utilized due to inconvenient overall planning, large investment, small income, and inability to produce benefits. For example, solar energy, wind energy or biogas bioenergy are difficult to provide continuous support for users to use electricity well. [0003] As a controllable renewable clean energy, biogas can alleviate the energy crisis, reduce greenhouse gas emissions and improve the environment by making full use of biogas. The construction of biogas projects is blooming everywhere. However, the current utilization of biogas...

Problems solved by technology

[0004] The disadvantage of the above-mentioned method 1 and the above-mentioned method 2 is that if one or more biogas power generation devices fail, it will directly affect the power consumption of users.

The disadvantage of the above method 3 is that a certain amount of equipment needs to be purchased for integration into the national grid, which will bring peak-shaving impacts to the grid, and cause high management costs for grid peak-shaving, which may outweigh the gains.
