| In the park energy Internet, in order to realize the real-time control of the charging and discharging process of the energy storage elements, the 2V, 200 Ah valve-regulated lead acidbattery is taken as the research object. According to the supply side environment, experimental data and existing data of the energy system, a nonlinear dynamic equivalent circuit model is established, which takes into account electricity, heat, nonlinear behavior and temperature estimation. Through the model, the influence of different discharge rates on the capacity of energy storage equipment, the function of the nonlinear parameters of the battery related to the current and open circuit voltage, and the influence of the battery temperature on the internal parameters are studied. The model results match the experimental results completely, which provides a certain reference value for improving the energy storage configuration. |
