Abstract

The renewable energy systems (RESs) are an attractive option to electrify the community as they are environment friendly, free of cost, and all-pervading. The efficiency of these energy systems is very low and can be improved by integrating them in parallel. In this paper, hydro (7.5 kW) and solar systems (10 kW) are taken as RESs and connected with the utility grid. Due to the intermittent nature of both the hydro and photovoltaic energy sources, utility grid is connected to the system for ensuring the continuous power flow. The hydro power generation system uses the self excited induction generator (SEIG) and converters. The AC/DC/AC converter is used as interface to connect the hydro turbine to the utility grid to adjust the generated voltage to the utility grid voltage. The solar generation system is the combination of PV array, boost converter, and solar inverter. The control of both the hydro and solar power plants is provided through the constant current controller. The analysis has been done to verify the existence of the proposed system. Results demonstrate that the proposed system is able to be put into service and can feed the community.

水电太阳能并网混合动力系统性能分析

可再生能源系统(RESs)是一个有吸引力的选择，因为它们是环保的，免费的，无所不在的。这些能源系统的效率非常低，可以通过并联集成来提高效率。本文将水电系统(7.5 kW)和太阳能系统(10 kW)作为RESs并网。由于水电和光伏能源都是间歇性的，为了保证电力的持续流动，公用电网与系统相连。水力发电系统采用自激感应发电机(SEIG)和变流器。AC/DC/AC变换器作为水轮机与电网连接的接口，将水轮机产生的电压调节到电网电压。该太阳能发电系统由光伏阵列、升压变换器和太阳能逆变器组成。水电和太阳能发电厂的控制都是通过恒流控制器提供的。通过分析验证了所提出系统的存在性。结果表明，所提出的系统能够投入服务，并可以为社区提供服务。
