Power-to-gas equipment capacity optimization configuration method giving consideration to wind power consumption

Abstract

The invention provides a power-to-gas equipment capacity optimization configuration method giving consideration to wind power consumption, and the method comprises the following steps: 1), obtaining the wind power output and the power and natural gas load data of a region last year where a power-gas combined network is located; 2), obtaining the parameters of a generator, a gas source and power-to-gas equipment in the network; 3), giving consideration to the constraint from the power-to-gas equipment, introducing a winding curtailment quantity as a penalty term, and building a power-gas combined network yearly cost optimal model; 4), solving the power-gas combined network yearly cost optimal model through employing a primal-dual interior point method, and obtaining the minimum yearly cost of the combined network and an optimization configuration capability of the power-to-gas equipment at this moment. The method provided by the invention achieves the configuration of the capacity of the power-to-gas equipment in the network, and can effectively reduce the yearly cost and wind curtailment rate.

Description

technical field [0001] The invention relates to a method for configuring the capacity of power-to-gas equipment, in particular to a method for optimizing the capacity of power-to-gas equipment considering wind power accommodation. Background technique [0002] As a new type of energy conversion technology, power-to-gas technology has changed the status quo of one-way conversion of natural gas to electricity through gas turbines, and made the coupling between the power grid and the natural gas grid more closely. After the power-to-gas technology is applied in the electricity-gas joint network, it not only enhances the coupling of electricity and natural gas, and promotes the optimal operation of multi-energy flows, but also converts surplus wind energy into natural gas during periods of high wind power generation, which contributes to reducing Curtailment provides a new approach. [0003] The introduction of power-to-gas equipment in the electricity-gas joint network (a netw...

AI Technical Summary

Problems solved by technology

As the capacity of power-to-gas equipment increases, the proportion of wind curtailment will also decrease, but due to the constraints of the operation of the power grid and natural gas network, the decline will decrease with the increase of power-to-gas capacity

Today's power-to-gas technology is still in its infancy and investment costs are still very expensive
