A decision-making method for joint start-stop control of generator set and heat exchange station

Abstract

The invention relates to a decision-making method for joint start-stop control of a generator set and a heat exchange station, and belongs to the technical field of power system operation. This method establishes a decision-making model for joint start-stop control of generating units and heat exchange stations. This model uses the minimization of the total power generation and heating costs of conventional thermal power units and heating thermal power units as the objective function. The constraints include power system constraints and supply constraints. Thermal system constraints. This method uses the large M method to perform an equivalent transformation on the established control decision-making model for the joint start and stop of the generator set and the heat exchange station, and finally solves the obtained mixed integer quadratic programming problem to obtain the joint start and stop of the generator set and the heat exchange station plan. This method can avoid the risk of insufficient power and heat supply brought about by traditional control decision-making risks based on experience, and ensure the safety and reliability of power supply and heat supply. Na has improved significantly.

Description

technical field [0001] The invention relates to a decision-making method for joint start-stop control of a generator set and a heat exchange station, and belongs to the technical field of power system operation control. Background technique [0002] Combined heat and power technology has great potential and benefits for improving energy efficiency, promoting the consumption of renewable energy such as wind power, and reducing carbon emissions. North my country is vigorously developing combined heat and power technology. The heating thermal power unit is not only the main source of electricity, but also the main heat source of the urban heating system. Constrained by the constraints of the thermal power unit's own output, it must maintain a relatively high level of minimum electrical output to ensure sufficient heat supply, which in turn leads to insufficient wind power accommodation space and even affects power supply security. However, the combined heat and power system ha...

Problems solved by technology

Constrained by the constraints on the output of heating thermal power units, they must maintain a relatively high level of minimum electrical output to ensure sufficient heat supply, which in turn leads to insufficient wind power accommodation space and even affects power supply security.

However, the combined heat and power system has a complex structure, and the traditional start-stop control method is based on experience, which cannot guarantee the safety of power supply and heat supply.
