Natural gas and water resource coordinated power generation optimized operation method

Abstract

The invention discloses a natural gas and water resource coordinated power generation optimization operation method. The method comprises the following steps: establishing an additional gas-power allocation mechanism; the apportionment cost is included in the total cost of gas-water bundling delivery by using an apportionment mechanism, and a gas-water bundling delivery cost model is constructed; determining a gas-electricity-water-electricity bundling delivery unit price based on a receiving end electric quantity game, and establishing a gas-water bundling delivery income model; combining the gas-water bundling delivery cost model and the gas-water bundling delivery income model to establish a gas-water coordinated power generation total cost and income model; and power generation optimization is carried out based on the gas-water coordinated power generation total cost and income model. A gas-water bundling delivery mode is adopted for coordinated dispatching with water and electricity, the power generation carbon emission is reduced, the seasonal imbalance problem of abundant and few water and electricity is solved, the peak regulation capacity of the system and the clean energy consumption rate are improved, and meanwhile multi-energy coordinated optimization operation is achieved.

Description

technical field [0001] The invention relates to the technical field of power generation, and more particularly to a method for optimal operation of natural gas and water resources coordinated power generation. Background technique [0002] There are many ways for multi-energy coordinated power generation to solve the dilemma of water abandonment. Most of the current research is to use wind power, photovoltaic or thermal power, nuclear power, energy storage devices, etc. to coordinate power generation with hydropower. The randomness and volatility of wind power and photovoltaics will have a great impact on the stability of the power system. Nuclear power and energy storage are difficult to popularize due to scale restrictions. Thermal power can not be an advantage in coordinating medium and long-term operation of hydropower due to its large pollution to the environment. . [0003] From the perspective of development status at home and abroad, a wind-light-water-gas-fire-stor...

AI Technical Summary

Problems solved by technology

Although the use of natural gas power generation to coordinate hydropower can promote natural gas consumption and improve system stability, if only internal coordinated power generation is considered, it will fall into a development deadlock due to the high cost of gas-power operation and maintenance, and there is currently no reasonable model for gas-water coordinated power generation to deal with this problem
