Problems solved by technology

Among them, stochastic optimization is based on the premise of obtaining the precise distribution of wind power, while robust optimization does not require an accurate probability distribution function. However, due to the disadvantage of conservative solution results in robust optimization, it may have adverse effects on the economy and environmental protection of the system.

Embodiment Construction

[0091] In recent years, wind power has taken a higher priority due to its clean, renewable, and flexible installed capacity. However, the volatility and intermittent nature of wind also make the grid connection of wind power uncertain, leading to The optimal scheduling problem of the system is often difficult to fully absorb it, so it is necessary to optimize the scheduling of the integrated energy system interval. like figure 1 , is the structural diagram of the electric heating integrated energy system.

[0092] 1. Calculation example description: The integrated energy system of the present invention includes 1 wind farm (200MW), 1 CHP unit (electrical capacity 300MW), electric efficiency is 0.41, heat capacity is 350MW, and thermal efficiency is 0.52. The CHP unit operates in the electric constant heat mode. One boiler has a heat capacity of 20MW, one heat pump unit has an electric capacity of 20MW, the COP coefficient of the heat pump unit is 3.5, and the time interval Δt...

Abstract

The invention belongs to the technical field of integrated energy systems, and particularly relates to an interval optimization scheduling method for an integrated energy system. The economical efficiency of the comprehensive energy system is optimized, and meanwhile abandoned wind consumption is promoted. Comprising the following steps: step 1, determining a comprehensive energy system structure, and establishing an electric heating comprehensive energy system optimization operation model based on a comprehensive energy system; and step 2, establishing an interval optimization strategy of wind power uncertainty.

Description

technical field [0001] The invention belongs to the technical field of comprehensive energy systems, and in particular relates to a method for optimal dispatching of intervals of comprehensive energy systems. Background technique [0002] In recent years, wind power has taken a higher priority due to its clean, renewable, and flexible installed capacity. However, the volatility and intermittent nature of wind also make the grid connection of wind power uncertain, leading to The optimal scheduling problem of the system is often difficult to fully absorb it, so it is necessary to optimize the scheduling of the integrated energy system interval. [0003] In the optimization of traditional wind power systems, stochastic optimization and robust optimization are generally adopted to deal with the uncertainty of wind power. Among them, stochastic optimization is based on the premise of obtaining the precise distribution of wind power, while robust optimization does not require an ...
