      ABSTRACT: In current energy market environment, interconnection among multiple integrated
community energy systems ( ICESs) and uncertainties of forecasting errors of PV and electric load are not
fully considered in ICES optimal dispatching. In this regard, in this paper, day - ahead optimal
dispatching of multiple ICESs is studied based on interval linear programming. Uncertainties of PV output
and electric load are both described with interval numbers. Aiming at maximizing interests of energy
service company ( ESCO) , an interval linear programming model is built to get day - ahead optimal
dispatching of multiple ICESs, where objective function and decision variables are represented with
appropriate interval numbers. Aspects of multi - energy interaction, network constraints, environmental
benefit and time-of-use ( TOU) price are considered together in above model. The model is solved with
enhanced interval linear programming ( EILP) . EILP contributes to ensuring feasibility of whole solution
space. Simulation results show that under background of multiple ESCOs taking part in transaction,
interconnection of multiple ESCOs with distribution network can increase total ESCO profit. Optimal
solution in form of interval can provide more options for decision makers, and reflect effects of
uncertainty factors on ESCO profit more actually.
