Control Strategy and Operation Optimization of CCHP with Solar Integrated Utilization

With characteristics of high efficiency and less pollution, combined cooling heating and power system, which can realize the energy cascade utilization, will become the development trend of distributed energy supply system in the future. Under this circumstance, this paper aims to design a co-supply system combining solar integrated utilization of PV/PT technologies with thermally activated technologies. The comprehensive evaluation index is obtained by constructed methods of judgment matrix considering energy conservation, environmental protection and economy integrally. The paper proposes three different control strategies of two different operation modes of OPH and OHP respectively. The effectiveness and feasibility of the proposed model were verified by system analysis of optimal refrigerating capacity ratio, optimal PV power generation capacity and the evaluation of control strategies.
