doi:10.3969/j.issn.1000-7229.2018.12.011

Abstract

Abstract: Integrated energy system is composed of multiple energy systems. When a combined heat and power unit fails, more than one energy systems can be influenced. Therefore, it is very important to improve the reliability of CHP. In this paper, we propose a maintenance decision model for CHP based on opportunistic maintenance. Firstly, the expression of the availability of CHP considering opportunistic maintenance is derived. And then, in order to quantify the impact of different maintenance strategies on system operation, system operation risk is given, taking electric load loss and heat load loss into account. Finally, maintenance decision model of the CHP is established with maintenance constraints. The model is solved by genetic algorithm. Case studies show that the model can optimize CHP maintenance strategy and improve the reliability of CHP and the overall system efficiency.

Key words: combined heat and power unit, opportunistic maintenance, maintenance risk, failure risk, maintenance decision
