Summary: This paper proposes a chance-constrained programming model for the design and energy dispatch management of a hybrid solar CCHP system considering uncertainties of solar energy and building loads. Uncertain scenarios are generated using Latin hypercube sampling and clustering methods. The model transforms stochastic optimization into deterministic optimization based on these scenarios. A multi-objective optimization model is then established, considering economic, energy, emission, and flexibility performances, and Pareto solutions are obtained using the modified ε-constraint method. A case study validates the proposed model and evaluates the impacts of confidence level on the optimization results.

Theoretical simulation is conducted to analyze the correlation mechanism of the piston assembly. The research shows that the thermally-driven pump can greatly reduce power consumption and has potential for industrial applications.
