Abstract
The invention provides an integrated energy system (IES) optimal configuration method considering energy storage full-life-cycle operation and maintenance, which comprises the following steps of: thestep 1, establishing a mathematical model for equipment except for energy storage of an IES; the step 2, constructing an energy storage mathematical model considering factors such as charge-dischargepower, charge-discharge state, capacity attenuation, charge state and power balance in the charge-discharge period; the step 3, comprehensively considering the whole life cycle cost and primary energyconsumption of the system to establish an IES optimal configuration target function; and the step 4, giving an IES optimization configuration constraint, and solving the established IES optimizationconfiguration model by using an optimization solver. According to the method, the effect of energy storage in the IES is emphasized, and the energy storage model comprehensively considers capacity attenuation and other factors, so that the method is more practical; and a comprehensive optimal result of economy and energy conservation is obtained, and the weight can be selected according to the actual situation.
Description
technical field [0001] The invention relates to the field of optimal configuration of integrated energy systems, in particular to a method for optimal configuration of integrated energy systems considering the operation and maintenance of the entire life cycle of energy storage. Background technique [0002] With the development of society and economy, people pay more and more attention to environmental issues and efficient use of energy. As far as our country is concerned, our country is relatively deficient in energy, and what is more serious is that our country's energy utilization efficiency is very low. Compared with developed countries, it only accounts for 62% of its energy utilization rate, and the phenomenon of waste is extremely serious. At the same time, my country's CO 2 China's emission ranks second in the world, exceeding 3 billion tons, accounting for almost the world's CO 2 13.6% of the total amount discharged. In order to solve the current problems of sub...
