Abstract

With increasing use of intermittent renewable energy sources, energy storage is needed to maintain the balance between demand and supply. The renewable energy sources, e.g. solar and wind energy sources, are characterized by their intermittent generation, causing fluctuations in power generation, and, similarly, demand may vary. There may be fluctuations in power generation, and, similarly, demand may vary. Then, for these new sources become completely reliable as primary energy sources, energy storage is a crucial factor. This work uses real-time simulation to analyze the impact of battery-based energy storage systems on electrical systems. The simulator used is the OPAL-RT/5707™ real-time simulator, from OPAL-RT Technologies company. The simulated system consists of a three-phase inverter connected to a BESS (battery energy storage system) and to the electrical grid with variable loads. The obtained results from real-time simulations prove its effectiveness for this type of analysis and open the possibility to perform PHIL (power hardware in the loop) simulations.

面向电网冲击分析的电池储能系统建模与仿真。

随着间歇性可再生能源的使用越来越多，需要储能来维持供需平衡。可再生能源，如太阳能和风能，其特点是间歇性发电，造成发电量波动，同样，需求也可能变化。发电量可能会有波动，同样，需求也可能有所不同。然后，为了使这些新能源成为完全可靠的一次能源，储能是一个至关重要的因素。这项工作使用实时仿真来分析基于电池的储能系统对电力系统的影响。所使用的模拟器是OPAL-RT/5707™实时模拟器，来自OPAL-RT技术公司。仿真系统由一个三相逆变器组成，该逆变器连接到BESS(电池储能系统)和可变负载电网。通过实时仿真得到的结果证明了该方法对此类分析的有效性，并为进行电源硬件在环仿真提供了可能。
