Research On Bi Level Optimization Of Configuration And Operation Of Multi Type Clean Heating System

In order to solve the problem of energy shortage and increasingly serious environmental pollution,electric heat storage technology as clean heating has been developed rapidly.However,a single electric heat storage device has high investment cost,narrow application range and low equipment utilization rate,which can not meet the needs of the rapid development of the energy system.Therefore,this thesis proposes a multi sort clean heat,that is especially electric heat storage heating and equipped with alternative clean heating devices,which may be employed in a spread of situations,thus on improve the association between numerous energy systems and compose for the technical defects and use restrictions of one instrumentality.Firstly,this thesis introduces the physical framework of multi sort clean heat thoroughly,and formulates an affordable cooperative coming up with method consistent with operation characteristics of the system.Supported the analysis of the economic and technical characteristics of electrical heat device and also the operation method of typical instrumentality,the mathematical model of typical instrumentality is established.Then,a two-level improvement model of multi sort clean heat considering the minimum operation and maintenance value and also the minimum investment value is made.The perfect model aims at rock bottom total investment price,together with the initial investment price of electrical heat storage instrumentality and alternative energy provide instrumentality.The objective function of the lower model is to minimize the total operation cost and maintenance cost when the investment cost of the upper model is the lowest.Benders Decomposition method is used to solve the upper level problem and the lower level problem interactively until the objective function reaches the optimal value.Finally,so as to satisfy the requirements of environmental protection,the operation improvement model of unpolluted heat with emission reduction advantages is made.The targer operate determines the importance of operation and maintenance prices and environmental indicators to the system by exploitation weight coefficients.Use the yalmip tool chest in MATLAB to compile and decision the CPLEX convergent thinker to unravel,thus on improve the answer speed and accuracy.The analysis system of emission reduction advantages is established to judge the emission reduction effects of operation planning results with emission reduction advantages.This thesis selects 2 situations of residents and trade,namely,the clean heating and cooling project of a collective village in Hopeh and also the clean heating technology transformation project of a coalpit in state Autonomous Region.The rationality of the double-layer planning model and also the operation potency of the double-layer planning formula square measure verified.Finally,the operation planning improvement with emission reduction advantages is disbursed for the instance,and also the emission reduction advantages analysis system is employed to judge the operation results of the system.
