Abstract

The invention discloses a thermoelectric combined system scheduling method for achieving wind power absorption based on energy storage of a centralized heat supply pipe network and buildings.The thermoelectric combined system scheduling method includes the following steps that S1, a wind power absorption thinking based on energy storage characteristics of the centralized heat supply pipe network of a thermoelectric combined system and the buildings is proposed; S2, thermal dynamic characteristics of the centralized heat supply pipe network and the buildings are analyzed; S3, a thermoelectric combined system optimization scheduling model is established based on the energy storage characteristics of the centralized heat supply pipe network and the buildings; S4, coordinative optimization is conducted on hour-by-hour power supply of energy supply bodies of a power system and a thermodynamic system in the thermoelectric combined system according to the solution to obtain an optimal control strategy for achieving in-regional wind power absorption and cross-regional wind power coordinative absorption.The method can change an original local wind power absorption mode, integrates the characteristics that electric energy is easy to transmit and is not easy to store and heat energy is easy to store but is not easy to transmit and achieves the purposes of wide-area interaction between wind power and thermal power and wide-area wind power absorption.

Description

technical field

[0001] The invention relates to the field of coordinated scheduling control of combined heat and power systems, in particular to a scheduling method for combined heat and power systems based on central heating pipe networks and building energy storage to accommodate wind power. Background technique

[0002] With the increasingly serious problem of environmental pollution and the problem of comprehensive optimization and adjustment of energy structure, the awareness of developing new energy sources in all countries in the world is constantly strengthening. Wind power, as a representative of renewable energy power generation with the largest development scale, has received more and more attention in recent years, and its development and utilization have developed rapidly. However, because wind power output depends on the wind, it is unstable in time and unbalanced in space. The characteristics of randomness, volatility, and anti-peak regulation make the consump...
