Real-time scheduling demand determination method for thermal power units considering maximization of new energy acceptance

Abstract

The invention relates to a thermal power generation unit real-time dispatching requirement determination method considering maximum new energy utilization, and belongs to the technical field of operation and control of a new energy access power system. The method comprises the steps of starting data acquisition for one time at the current moment; calculating the real-time power generation requirement of the current power grid; calculating the output regulation requirement of the current automatic control unit obtained under different conditions in real time; calculating the regulation requirement of the current call wire power obtained under different conditions in real time; and finally obtaining the real-time dispatching requirement of the thermal power generation unit of the power system considering the maximum new energy utilization, and carrying out corresponding real-time dispatching on the thermal power generation unit of the power system under different conditions in real time. According to the method, the maximum new energy power generation utilization is taken as the target, so that the power system can arrange the thermal power generation unit output in advance according to the new energy power generation operating state and the power grid operating state in real time so as to fully develop the power grid regulation capacity and ensure that the power grid has enough regulation space to utilize the new energy.

Description

technical field [0001] The invention belongs to the technical field of operation and control of a new energy access power system, and in particular relates to a method for determining real-time dispatching demand of thermal power units in a power system considering maximization of new energy acceptance. Background technique [0002] The strong randomness of wind and light resources, the difficulty of forecasting, and the reverse peak regulation make the active power dispatching and control of the power grid more difficult. Under the premise of ensuring the safety of the power grid, how to maximize the use of new energy power generation resources and absorb as much new energy power generation as possible has become one of the common challenges faced by the power grids where all new energy power generation bases are currently located. At present, the industry has conducted a lot of research on the active power dispatching control after the access of new energy generation, and ...

Problems solved by technology

This method only considers the second-level adjustment ability of the automatic generation control unit, and does not adjust the output of thermal power units with minute-level adjustment ability in the power grid in advance, so it does not make full use of the power grid adjustment ability, and does not achieve the new energy that maximizes the acceptance of new energy. The demand for priority scheduling has led to curtailment of wind or solar power due to insufficient estimation of the grid's capacity to accommodate new energy generation, reducing the utilization rate of new energy power generation
