Exergy analysis of an integrated molten carbonate fuel cell-turbo expander-steam turbine hybrid cycle has been presented in this study. The proposed cycle has been used as a sustainable energy approach to provide a micro hybrid power plant with high exergy efficiency. To generate electricity by the mentioned system, an externally reformed molten carbonate fuel cell located upstream of the combi...

Combined cooling, heat, and power (CCHP) units can be integrated with conventional separate cooling, heat, and power production units to meet demands. The goal of this study is to develop and examine a hybrid GA-heuristic optimization algorithm for solving the unit commitment problem for integrated CCHP-thermal-heat only system with considerations for electricity boiler. When environmental emis...

Abstract: In the last few years, due to the development of the new equipment in power systems, challenges have appeared in their planning and operation. One of these issues is the development of combined heat and power (CHP) units. These units have the capability to generate heat and electricity simultaneously according to their limitations. Hence, it is necessary for them to think about the ar...

Utilizing the combined cooling, heating and power generation (CHP) systems to produce cooling, heat and electricity is growing rapidly due to their high efficiency and low emissions in commercial and industrial applications. In conventional CHP systems the deficit of the system power can be purchased from the grid. However, this system cannot be used as the standalone application. The hybrid so...

This paper proposes a distributed real-time state estimation (RTSE) method for the combined heat and power systems (CHPSs). First, difference-based model system is established considering dynamics of systems. further used along with steady-state holistic CHPS estimation. A cubature Kalman filter (CKF)-based RTSE developed to deal nonlinearity while integrating both historical present measuremen...
