Embodiment Construction

[0033] This embodiment makes full use of natural energy to supply energy for daily loads required by residents of remote islands, and establishes a green island ecosystem in which the power network, gas network and heating / cooling network are coupled with each other. The power network energy mainly comes from the island's abundant solar and wind energy, and uses natural energy combined with solar photovoltaic and offshore wind power generation technologies to meet the electricity consumption of island residents. The main energy source of the heating / cooling network comes from geothermal energy and solar energy, and the energy provides residents with hot water and indoor temperature control services through carrier water and carrier heat transfer oil. The gas network is a large-scale energy storage network. Under the premise that natural energy is abundant and the other two networks meet their own load requirements, the other two networks will supplement energy for the gas netwo...

Abstract

The invention discloses an island multifunctional ecological energy system. The system comprises a power generation unit, an energy storage unit, a power network, a power load, a heat / cold load, a gasnetwork, a heat / cold network, and a cold-heat-power triple generation system; the power generation unit, the energy storage unit and the power load are connected with the power network; the power network is connected with the gas network through an air compressor, the power network is connected with the heat / cold network through a heat pump, the heat / cold network is connected with the heat / cold load, the gas network and the heat / cold network are connected with the cold-heat-power triple generation system; and the cold-heat-power triple generation system is connected with the power network through a generator. The energy among the power network, the gas network and the heat / cold network is mutually coupled so that the stability of the energy source is much greater than the stability of thesingle network; according to the natural advantages of the island, the natural energy of the island is used for providing for the own; the supplied energy is green and pollution-free, and the problems of uneconomic and environment pollution caused by long-distance power transmission and traditional heat-engine plant establishment are avoided.

Description

technical field [0001] The invention belongs to the field of energy production and supply, and in particular relates to an island multifunctional ecological energy system. Background technique [0002] A green multifunctional ecosystem is a green ecosystem composed of multiple energy networks that can supply various loads of the system. It is mainly composed of electricity network, gas network and heat / cold network. Each energy network directly or indirectly provides energy for various loads in the system. In the island areas where the power grid is difficult to reach, the power supply is difficult to guarantee, which affects the life of the island residents. The current new energy power generation, such as wind power generation and solar power generation, has the characteristics of randomness and intermittent nature, which are not conducive to the stability of the power system. [0003] In order to ensure the stability of the power system, it is urgent to study an island...
