Abstract In order to realize high economical and energy-saving potentials of local
energy system, it is necessary to determine its structure rationally by selecting some
kinds of equipment from many alternative ones so that they match energy demand
requirements for an objective user. It is also important to determine rationally the
number and capacities of each kind of equipment selected and the system’s annual
operating strategies corresponding to hourly variations in energy demands. Facing
the abovementioned problems, a systematic optimization procedure is needed. The
role of optimization is to reveal the best (under certain criteria and constraints)
design and the best operational point of local energy system automatically, with
no need for the designer to study and evaluate one by one the multitude of possible
variations. It is a time-dependent optimization and without pre-specification, so the
degree of freedom is very large, and the problem is very complex. Energy models
have been widely used for solving this problem. This chapter attempts to develop a
general method to find an optimal integrated system among different distributed
energy combinations for a local community, minimizing the total energy cost
(sometimes carbon emissions and primary energy consumptions as well) while
guaranteeing reliable system operation. PV, wind, CHP, and energy storage are
considered in the model.
