Abstract

The invention discloses a high-speed service area storage and charging integrated system based on miniature biogas fermentation, and belongs to the field of new energy storage and charging systems. The system comprises a miniature fermentation tank, a solar water heater, a hot water tank, a gas storage unit, a power generation unit, a power storage unit and a charging pile, the miniature fermentation tank is provided with a feeding device, hot water of the solar water heater is connected with the hot water tank, the hot water tank is connected with the miniature fermentation tank and the feeding device, and the miniature fermentation tank is connected with the gas storage unit. Biogas in the gas storage unit generates power through the power generation unit, the power generation unit is connected with the power storage unit, and the power storage unit provides power for the charging pile. The invention aims to solve the problem that a novel electric power system mainly based on renewable energy sources is constructed on an expressway to provide electric power for new energy automobiles for charging, source energy sources such as biogas power generation and energy storage are efficiently and valuably used, and the social value of energy conservation and emission reduction of the new energy sources is fully exerted. And through regional regulation and control, the peak demand is reduced, and the power use cost is reduced through peak clipping and valley filling.

Description

technical field [0001] The invention relates to a new energy storage and charging system, in particular to a high-speed service area storage and charging integrated system based on micro-biogas fermentation. Background technique [0002] At present, electricity is the main form of my country's energy consumption side. Building a new type of power system based on renewable energy will be the main development direction of the country's current and future energy strategies for a long time. Solar energy and wind energy resources are very rich in northern my country. However, due to the strong randomness, intermittent and uncontrollable nature of solar energy and wind energy, as the proportion of renewable electricity increases in the future, the impact on the power grid will be greater.

Problems solved by technology

Solar energy and wind energy resources are very rich in northern my country. However, due to the strong randomness, intermittent and uncontrollable nature of solar energy and wind energy, as the proportion of renewable electricity increases in the future, the impact on the power grid will be greater. How to realize the stable operation of the power grid will face severe challenges. Distributed renewable energy is the future development direction, among which distributed charging and discharging stations are the general trend and may even become standard equipment. Although distributed photovoltaics have many advantages, However, there are still some challenges in the promotion process: there are various types of roofs, and the design, construction and post-operation and maintenance management are difficult; the power station is close to the user side, and safety issues are prominent; a large number of distributed photovoltaic power stations are connected to the consumption capacity and stability of the distribution network. operation has a greater impact, etc.

In addition, the rapid growth of new energy vehicles and residential loads also brings great challenges to the distribution network

The randomness, disorder and large-scale access of new energy vehicle charging access will directly lead to the problem of "peak on top" of the distribution network
