摘要：

In order to cope with the randomness，intermittency and uncertainty of wind power generation in the“Three North”region，particularly during periods of high wind power generation，the operation mode of coal-fired Cogeneration units that“determine power by heat”is insufficient for flexible adjustment. For this reason，the Latin hypercube sampling method is used to simulate the next day’s wind and power output scenario，determine the spinning reserve based on a certain confidence level，and optimize the rotating reserve capacity of virtual power plant by providing power reserve through carbon capture equipment. A day-ahead stochastic optimal scheduling model of combined heat and power of virtual power plant containing carbon capture thermal power units is established，and the model is solved by using quadratic interpolation method and adaptive genetic algorithm. The simulation shows that the auxiliary power reserve of carbon capture equipment can balance the reserve of rotating reserve and low-carbon operation of virtual power plant，reduce wind and solar curtailment，reduce the cost of rotating reserve，and realize safe and low-carbon economy operation of power system. © 2024 Science Press.
