Description

Technical Field

[0001] The present invention relates to the technical field of power regulation, and in particular to a method for predicting the power regulation capability index of an electric boiler coordinated with a gas boiler. Background Art

[0002] Against the backdrop of an accelerating global energy transition, electric boilers, as a core provider of clean thermal energy, have become a key technology for supporting a high proportion of renewable energy consumption due to their flexible regulation and grid interaction. Compared to traditional gas-fired boilers, electric boilers offer advantages such as reduced carbon emissions and faster response times due to thermal-electrical decoupling. They are finding large-scale application in areas such as district heating and industrial steam generation. By coordinating the operation of gas and electric boilers, efficient energy utilization can be achieved, improving overall system efficiency and resilience.

[0003] Currently, electric boiler power regulation is suitable for balancing grid power over longer timescales. However, due to the uncertainty of renewable energy sources and loads in the power system, the power regulation requirements of the power system are also subject to uncertainty. Furthermore, existing regulation methods fail to comprehensively assess and predict the power regulation capabilities of electric boilers, making it difficult to implement timely and accurate regulation measures in emergency situations.

[0004] To address these issues, it is necessary to propose a method for predicting the power regulation capability index of electric boilers coordinated with gas boilers. When the output power of the electric boiler is insufficient, it can be predicted in advance and coordinated with the output power of the gas boiler to achieve a stable state and ensure the system load demand.

The method for predicting the power regulation capability index of an electric boiler coordinated with a gas boiler according to claim 1, characterized in that: The calculation t i+1 Prediction value of power regulation capability index of electric boiler coordinated by gas boiler at the moment The specific process is as follows: Calculate t i+1 The predicted value of the power regulation capability index of the gas boiler coordinated with the electric boiler at the moment is shown in formula (6): If the predicted value of the power regulation capability index of the electric boiler coordinated by the gas boiler is greater than 0.6871, the heating power of the gas boiler needs to be increased immediately, and the heating power of the electric boiler needs to be reduced to avoid thermal power redundancy; if the predicted value of the power regulation capability index of the electric boiler coordinated by the gas boiler is less than or equal to 0.6871, the heating power of the electric boiler needs to be increased, and the heating power of the gas boiler needs to be reduced to meet the heat load demand.
