For the dispatch operation of the cross-regional integrated energy system

considering the interaction of cooling

heating and power loads

this paper sets up the complementarity of the cooling and heating loads between regions

so as to build a cross-regional integrated energy system scheduling optimization model that meets multiple load requirements. Secondly

considering the uncertainty of wind power and photovoltaic power generation and the instability of market energy prices

the value-at-risk theory is introduced to construct a cross-regional dispatch optimization model that considers the cost of risk

and an example is analyzed for validation. The results show that

under the condition of meeting multiple load requirements

the realization of multi-energy complementarity through cross-regional system scheduling is efficient than resource utilization in individual region. At the confidence level of 0.9

the operating cost of gas

power consumption and dispatching reduces by 4.96%

2.00% and 2.87%

respectively.
