Interconnected type regional comprehensive energy system collaborative optimization method based on power-to-gas conversion

Abstract

The invention discloses an interconnected type regional comprehensive energy system collaborative optimization method based on power-to-gas conversion in the technical field of comprehensive energy. The interconnected type regional comprehensive energy system collaborative optimization method based on power-to-gas conversion comprises the following steps: S1, a target region comprehensive energy system device model is established; S2, a power grid provides gas to a gas network through a P2G technology, power and steam generated by the power grid and the gas network are respectively provided for a power supply device, a gas supply device and a heat supply device through a driving component; S3, the power grid receives power converted by photovoltaic power generation and wind power generation through a transformer; S4, the steam provided by the gas network is provided for combined heat and power generation and a gas-fired boiler, the generated heat energy is provided for users, residualsteam of production of combined heat and power generation is provided for power generation again or returned back to the power grid. Thus, full use of regenerative resource electric energy is realized, energy consumption cost is reduced, gas and power complementation between the power grid and the gas network is realized, and utilization rate of energy is improved.

Description

technical field [0001] The invention relates to the technical field of comprehensive energy, in particular to a method for collaborative optimization of a regional comprehensive energy system based on power-to-gas interconnection.

Problems solved by technology

[0003] In the traditional energy consumption model, the demand for energy is too much attached to electric energy, and the coal-fired power generation from the large power grid or the power of large natural gas generator sets are mainly used, which is too dependent on the power supply of the large power grid. When a certain transmission link of the power grid appears When a fault occurs, it will easily lead to a large-scale power outage, which will affect the energy demand of users; the large consumption of fossil energy such as coal will easily lead to environmental pollution problems. Renewable resource power such as photovoltaic power generation is not considered, and electric energy is used as a single energy input. Energy use system, energy use reliability is low
