User-side micro-energy network energy supply system

Abstract

The invention discloses a user-side micro-energy network energy supply system. The user-side micro-energy network energy supply system comprises a residential community micro-energy network, a commercial park micro-energy network, an industrial area micro-energy network and an agricultural area micro-energy network, wherein each of the residential community micro-energy network, the commercial park micro-energy network, the industrial area micro-energy network and the agricultural area micro-energy network comprises an input unit, an intermediate energy production, conversion and storage unitand an output unit; the input unit is connected with an external power grid, a municipal heat supply network and a natural gas network, is also connected with other micro-energy networks, and inputs electric energy and heat energy of the other micro-energy networks; the intermediate energy production, conversion and storage unit comprises a cold bus, a heat bus, an electric bus, an energy conversion device and an energy storage device; and the output unit outputs cold, heat and electricity to meet cold, heat and electricity requirements of users in the micro-energy networks, redundant electricity is connected to the networks or is supplied to the other micro-energy networks, and redundant heat energy is supplied to the other micro-energy networks. The user-side micro-energy network energysupply system can realize clean and efficient, energy-saving and environment-friendly gradient utilization, complementary coordination, safety and high quality of the whole process of energy production, transmission and utilization.

Description

technical field [0001] The invention belongs to the technical field of power grids, and in particular relates to the technical fields of micro-grids and comprehensive energy systems. Background technique [0002] my country is facing an "energy comprehensive era" in which new energy and fossil energy complement each other. Under the energy demand in the new era, my country urgently needs to take a new round of technological revolution and industrial revolution as the fulcrum, and change from the previous extensive development model to a more intensive one. , sustainable development model, and establish a more efficient, safe and sustainable energy utilization model. The distributed energy system provides an effective way for commercial or industrial users who need cold, heat, and electricity, as well as island power supply and mobile power supply, but the energy utilization method of the distributed energy system is distributed "in-situ collection, on-site storage, on-site U...

Problems solved by technology

The distributed energy system provides an effective way for commercial or industrial users who need cold, heat, and electricity, as well as island power supply and mobile power supply, but the energy utilization method of the distributed energy system is distributed "on-site collection, on-site storage, use", it is difficult to achieve coordination and mutual aid in a certain area

On the other hand, in the traditional energy system, different energy industries such as power supply, heating, and cooling are relatively closed, and the degree of interconnection is limited. Different systems are planned and operated in isolation, which is not conducive to the improvement of energy efficiency and the consumption of renewable energy.
