Research On Virtual Prototype Of Distributed Renewable Energy System

Utilization of renewable energy as a precondition, made the distributed energysystem as the main object of study, mainly analysis of the three systems about groundsource heat pump system solar photovoltaic system and solar thermal system. Departurefrom established mathematical model that the three systems, detailed description of thecomposition, working principle, the working efficiency of each system, and many otherissues, provide a theoretical basis for the system of quantitative calculations and energyanalysis.Based on the theoretical analysis and the mathematical model which had beenestablished to create a virtual prototype system, and base on the TRNSYS, MATLABsoftware platform to quantitative simulation for the virtual prototyping system. establishsingle building virtual models and calculate its load. On the other hand, get the actualproject working through field research of various systems. Combine theoretical analysisand practical engineering to get the scientific and rational experimental parameters.From basic physics of photovoltaic cells to describes the generation principle of aphotovoltaic cell and establish photovoltaic cell system model. Through analyzing andsummarizing the photovoltaic cell output characteristic curve and base on the MPPTtechnology to create a virtual model of photovoltaic power generation system; From themathematical model of ground source heat pump system to solve and analyze theindicators of the ground heat exchanger, made virtual single building as assumption,through the quantitative calculation to get the heat pump system’s cooling/heating rate indifferent conditioning and evaluating the overall energy efficiency at the same time;Trough comparing and analyzing of the three kinds of solar collectors to select theFlat-plate collector as the main object to research, through software simulation for solarthermal systems to get the efficiency and heating capacity.Integration of three subsystems and propose ideas on the concept, integration of thethree systems which of solar photovoltaic system solar thermal system and groundsource heat pump system and expecting to achieve efficient use of renewable energysources in a distributed energy framework.Put forward the overall solution of distributed renewable energy systems, includingthe composition and the ratio of energy, outlining the blueprint of the distributed renewable energy systems which had been integrated.
