Optimizing Industrial Facility’s Demand for Combined Heat-and-Power (CHP)

Abstract

There is no work able to handle with minimizing costs of a CHP based-district energy system in the face of uncertain manufacturing currently available. This study is therefore has a goal of establishing a methodology applicable to future supporting engineers and decision makers, asked to combine heat and electricity generation for optimising a DH system’s structure and production rates of an industrial facility. Both objective functions are expressed as the sum because they represent the total annual thermal energy and electricity. Yearly heat and electricity values are calculated and shown, that represents the correlation and the flexibility of the generation. It can be observed that the higher electricity demand is compensated by a higher electricity production at a CHP plant, thus reducing the payback period for generation equipment. In case of the increased heat production from a CHP, the level of electricity does not obligatory increase. The most relevant option in comparison to other values of electricity delivery concerning the introduction of thermal energy output is also identified. Although countries try to achieve energy efficiency targets, ordinary industrial facilities in the world still largely depend on production rates and associated heat loads. CHP plants perform as the best option to be facility of the next generation although, but there is still a tremendous potential to use an optimizing approach in a DH system. This assessment shows the way to control the combined generation of power and heat within a complex industrial facility and to make it smoother.
