Abstract

The use of rechargeable batteries to store and distribute extra energy from photovoltaics (PV) improves the efficiency of solar energy generation. This study constructs a solar power plant system that is linked to the grid network and includes battery energy storage. The efficiency of a hybrid solar power plant with integrated batteries and grid energy storage is demonstrated and evaluated in this study. This study is based on real-time testing to determine battery utilization when different electrical loads for office use are combined. The workload profile during peak hours of use, which correspond to the peak time of sunshine, is used to evaluate the system. The collected findings show that the degree of effectiveness of this hybrid power plant fulfills the power simulation. During the peak irradiation time, the maximum power is 2100 watts, whereas the needed power simulation, which is 1900 watts in this case, so the power efficiency percentage is 110.52%. It means that PV can satisfy the charged power while also supplying extra power to the battery for usage at low periods. During the 8-hour test, the calculation of cost savings revealed a savings in electricity expenditure of Rp. 14,373. The energy storage system's real operational needs were met by battery storage and PV.

使用锂离子电池和电池管理系统的高效混合能源智能系统

使用可充电电池储存和分配光伏（PV）产生的额外能量，可提高太阳能发电的效率。本研究构建了一个与电网网络连接的太阳能发电厂系统，其中包括蓄电池储能。本研究展示并评估了集成电池和电网储能的混合太阳能发电厂的效率。这项研究基于实时测试，以确定当办公室使用的不同电力负载组合在一起时电池的利用率。使用高峰时段（与日照高峰时段相对应）的工作负荷曲线用于评估系统。收集到的结果表明，该混合动力发电厂的效率达到了电力模拟的要求。在辐照高峰时段，最大功率为 2100 瓦，而所需的模拟功率在本例中为 1900 瓦，因此功率效率百分比为 110.52%。这意味着光伏发电在满足充电功率的同时，还能为蓄电池提供额外的电能，供其在低谷时段使用。在 8 小时的测试过程中，通过计算节约的成本，可以节省 14,373 印尼盾的电费支出。蓄电池和光伏发电满足了储能系统的实际运行需求。
