Problems solved by technology

Green energy devices are known in principle from the prior art and are used to supply housing, for example low-energy housing, energy-saving housing or zero-energy housing, with thermal energy and especially electrical energy, for example from renewable energy sources such as photovoltaic generators or small wind power plants current, but the household energy equipment in the existing technology is still too expensive, and the control system still has room for improvement

Embodiment Construction

[0022] The technical solution of the present invention will be further introduced below in combination with specific embodiments.

[0023] This specific embodiment discloses a distributed energy saving system in which a fuel cell is coupled with a green building, such as figure 1 As shown, including distributed power supply system and micro grid intelligent management system. The micro-grid intelligent management system includes the micro-grid; the distributed power supply system is connected to the micro-grid.

[0024] The distributed power supply system adopts the "peer-to-peer" and "plug-and-play" modes in the self-made control to connect to the feeder through the power electronic interface. The feeder is connected to the electrical load in the building, and a static switch is installed in the middle of the feeder, through which the connection between the grid and the power grid can be controlled. The distributed power supply system includes air-cooled proton exchange mem...

Abstract

The invention discloses a fuel cell and green building coupled distributed energy resource energy-saving system. The fuel cell and green building coupled distributed energy resource energy-saving system comprises a distributed power energy supply system and a mircogrid intelligent management system; the mircogrid intelligent management system comprises a mircogrid; and the distributed power energysupply system is switched in a mircogrid. A fuel cell is taken as main power supply equipment of a green energy-saving device, and the system has the effects of high efficiency, cleanness, start-stopflexibility, modularization, short installation time and no noise pollution; the distributed power energy supply system is formed by an air-cooled proton exchange membrane fuel cell stack, a solar photovoltaic power generation device and a wind drive generator, the influence of other renewable energy sources on building load intermittently is stabilized by adjusting the output power of the fuel cell, and the balance of power grid source charge can be realized.

Description

technical field [0001] The invention relates to a distributed energy saving system, in particular to a distributed energy saving system coupled with a fuel cell and a green building. Background technique [0002] Fuel cell systems are used in new green household energy systems due to their high energy density, high specific energy, and cleanliness and pollution-free. However, due to their limited specific power, and because fuel hydrogen is not easy to store and transport, fuel cell systems are often combined with other clean energy sources in a hybrid configuration. The waste heat generated by the fuel cell is very clean, and the waste heat of the high-temperature fuel cell has a high temperature and has high utilization value. Due to the intermittence and uncontrollability of photovoltaic and wind power generation, the generated electricity is called garbage electricity, and its grid capacity is strictly controlled by the grid company. Currently, its utilization efficienc...
