AI Technical Summary

Technical Problem

The existing off-grid green electricity direct-connection hydrogen and ammonia industrial parks suffer from large fluctuations in wind and photovoltaic power generation, making it difficult to continuously meet the stable power demand of electrolyzers and synthetic ammonia units, resulting in frequent equipment start-ups and shutdowns and low efficiency in the utilization of new energy sources.

Method used

The method of configuring and optimizing the long-term energy storage capacity of the green electricity direct-connection hydrogen-ammonia park is adopted. By constructing a set of wind and solar power output scenarios, establishing power and hydrogen balance constraints, calculating the optimal configuration scheme of energy storage capacity, and formulating the optimal scheduling scheme, the energy storage can store electricity when wind and solar power are in surplus and discharge when they are insufficient, thus smoothing power fluctuations.

Benefits of technology

This has improved the level of new energy consumption, reduced frequent equipment start-ups and shutdowns, increased equipment utilization and production process stability, reduced the number of infeasible production hours, enhanced the park's energy autonomy and power supply reliability, and controlled construction costs.

Abstract

The present application relates to a kind of green electricity direct connection electric hydrogen ammonia park long-time energy storage capacity configuration and optimization operation method, comprising: obtaining park basic parameters, select wind light scene s;Establish power balance constraint;Establish hydrogen balance constraint;Calculate the abandoned electricity of each scene, obtain the maximum abandoned wind and light scene;Calculate the optimal configuration scheme of energy storage capacity:Formulate the optimal scheduling scheme of each wind light scene with energy storage participation production;Calculate annual production index.The present application adopts "three-stage progressive process of maximum abandoned electricity solution-energy storage capacity configuration-optimal production scheme design", with maximum abandoned wind and light scene as the capacity standard, accurately locks the minimum energy storage capacity that can fully consume abandoned electricity through dichotomous search, which not only ensures that energy storage can cover the whole scene surplus power consumption demand, but also avoids capacity redundancy and excessive investment, improves new energy consumption level while controlling construction cost, realizes the balance of technical effectiveness and economic rationality.
