Abstract

The invention relates to the technical field of power grid planning, and provides an energy connection-based time sequence production simulation method and system. The method comprises the steps of monitoring a current time node, and judging whether current time reaches a time sequence production simulation time threshold or not; if yes, allocating an energy connection-based complicated power gridenergy load, simulating a running state of each power generator set, and forming a continuous load curve of corresponding time zone; calculating fee information generated by a power generation systemaccording to the formed continuous load curve; otherwise returning to the step of executing the current time node to monitor. By the method, the influence of an allocated load on system running by various load management modes can be more definitely evaluated, and real-time optimization under different conditions also can be achieved by changing constraint conditions such as machine set startingand stopping limitation and machine set output change rate.

Description

technical field [0001] The invention belongs to the technical field of power grid planning, and in particular relates to a time-series production simulation method and system based on energy interconnection. Background technique [0002] In recent years, with the continuous increase in the scale of the power system, the addition of intermittent energy sources such as wind power and solar energy, the construction of large-scale cross-basin multi-level hydropower stations, the access of various types of power sources such as nuclear power, pumped storage power stations, and gas turbines, and the power grid Factors such as the pattern of long-distance AC-DC hybrid transmission have greatly increased the complexity of power grid operation. How to optimize the system operation in a complex power grid environment, improve the system's energy-saving economy, and reduce the system's emission intensity has become an important issue for power grid planning. The operation optimization...
