Control method, device and system for combined running of wind power equipment and thermoelectric equipment

Abstract

The invention discloses a control method, device and system for combined running of wind power equipment and thermoelectric equipment. The control method for combined running of the wind power equipment and the thermoelectric equipment comprises the steps of determining a constraint condition of a thermal power and an electric power of the thermoelectric equipment, a constraint condition of an electric powder of the wind power equipment and a constraint condition of the sum of electric powers of the wind power equipment and the thermoelectric equipment according to an equipment parameter; determining an energy storage constraint condition of a regional thermal network according to an energy storage parameter; determining the electric power of the wind power equipment and the thermal powerand the electric power of the thermoelectric equipment on the premise that the constraint conditions are conformed, the thermal load demand of the thermoelectric equipment is satisfied and maximum benefit of a wind power equipment and thermoelectric equipment combined running system is taken as a target; and sending a wind power output absorption instruction to the wind power equipment, and sending a dispatching instruction into the thermoelectric equipment. By the control method, the running flexibility of the equipment can be improved, wind power absorption is effectively facilitated, the wind abandoned quantity is reduced, and the economic benefit is improved.

Description

technical field [0001] The embodiments of the present invention relate to the control technology of an integrated energy system, and in particular to a control method, device and system for the combined operation of wind power equipment and thermal power equipment. Background technique [0002] In recent years, wind power has developed rapidly all over the world, and the installed capacity of wind power in my country has become the first in the world. However, due to the randomness, volatility, and uncertainty of wind power output, wind power consumption has encountered a bottleneck, which has brought certain negative effects on the operation of the power grid. In addition, since the thermal power unit implements the operation mode of "heat-based power", the peak-shaving capacity of the thermal power unit is reduced, which further reduces the consumption of wind power and generates a large amount of curtailed wind. [0003] In this case, the advantages of the Energy Interne...
