Method, device and apparatus for stochastic production simulation of combined heat and power of integrated energy system

The invention discloses a stochastic production simulation method of combined heat and power of an integrated energy system, Installations and equipment, Considering that energy sources other than power units, such as renewable energy, can also have an impact on integrated energy systems. At first, that net power sequential load data is separated from the power sequential load data, according to the net power sequential load data and the heat load data, the initial joint probability density function of thermoelectricity is constructed, to ensure the accuracy of the initial thermoelectric jointprobability density function, by simulating the operation of the unit in the integrated energy system, according to the unit performance index, the initial combined thermoelectric probability densityfunction is modified to obtain the equivalent combined thermoelectric probability density function, Finally, the reliability index and economic index of the integrated energy system calculated by theequivalent thermoelectric joint probability density function are more consistent with the characteristics of multi-energy coordination and coexistence of the integrated energy system, and the accurate evaluation of the reliability and economic value of the integrated energy system is realized.
