Optimum Siting and Sizing of Distributed Energy Resources Taking into Consideration Hourly Operating Strategies

Abstract

In this paper, a distributed energy resource (DER) system plan and evaluation model is extended to include the design of district heating network. In the model, production and consumption of electric power and heat, power transmissions, transport of fuels to the production plants, transport of water in the district heating pipelines and storage of heat are taken into account. The problem is formulated as a mixed integer linear programming (MILP) model where the objective is to minimize the overall cost of the DER system. The solution gives the DER structure, i.e., which production units, heat transport lines and storages should be built as well as their locations, together with design parameters for plants and pipelines.
