Generator set and heat exchange station joint start-stop control decision making method

Abstract

The invention relates to a generator set and heat exchange station joint start-stop control decision making method, which belongs to the technical field of power system operation. A generator set andheat exchange station joint start-stop control decision making model is established. The objective function of the model is to minimize the total power generation and heat supply cost of conventionalthermal power units and heat supply thermal power units, and the constraints include power system constraints and heat supply system constraints. In the method, the established generator set and heatexchange station joint start-stop control decision making model is transformed equivalently by a large M method, and finally, an obtained mixed integer quadratic programming problem is solved to obtain a generator set and heat exchange station joint start-stop plan. The method can avoid the risk of insufficient power and heat supply caused by the risk of traditional experience-based control decision making, ensure the safety and reliability of power supply and heat supply, fully tap the thermal inertia and heat storage characteristics of the heat supply system and significantly improve the wind power absorption of the power system.

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.
