Abstract

In an inconsistent view of energy systems, the interaction between different energy carriers is not taken into account. In such a view, the considered problem is not well optimized. The idea of an integrated looking into several carriers has been proposed by creating the energy hub concept. Due to the simultaneous attention of all energy carriers, long-term planning and short-term operation have converted to complicated challenges. To this end, this study focuses on the energy hub operation for cost minimization. In addition to considering reliability indices for different loads, diversity constraint is regarded as a key point to increase energy security. Sensitivity analysis of the degree of diversity and its effects on operation costs and Expected Energy not Supply (EENS), play a vital role in the final decision. LINDOGlobal solver is employed in GAMS to implement Mixed Integer Nonlinear Programming (MINLP) model. A sample energy hub, considering three carriers in the input port and three loads in the output port, is used as a test system, and results are discussed in depth.
