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.

In this paper, a hybrid topology of FACTS devices has been investigated to improve stability features of static voltage. The primary assumption is a power system which has been located under SVC parallel compensation. HPFC forms a hybrid controller using IPFC series converters as a hybrid with existing parallel and passive compensator (SVC) in power system. Thus, simultaneous and independent control of active power flow can be reached through transmission lines and the exchanged reactive power values towards sending and receiving line. Using a hybrid structure makes the use of convertors to improve performance of the old and existing compensators in the power system possible. In this study, the power injection model (PIM) has been used to model series-parallel parts of hybrid power flow controller in Newton-Raphson load flow, and all have been simulated in M-file environment of MATLAB software. In order to investigate the effect of this controller on stability properties of static voltage, P-V curve of PQ buses of a prototype system has been evaluated in a continuous power flow (CPF) in M-file environment of MATLAB software. In the section of simulation results, SVC parallel compensation and UPFC series-parallel compensation are compared in terms of the amount of losses, active and reactive power, and improvement of the system’s loading limit with the proposed hybrid structure.

—Hybrid power system consists of different sources of electrical energy with different operating times during different seasons. Deployment of a hybrid power system is expected in rural areas. Supplying remote load systems such as rural telephony, hospitals, military etc.., where continuous power supply is required, can be realized with the combination of wind and solar power. The proposed topology is designed for telecom load which uses dual input dc-dc fused converter for combining solar and wind energy sources. For the further research and improvements in the proposed fused converter topology, it is necessary to know in detail the power flow from solar and wind sources to the load or to storage battery depending on different seasons. For various wind speed with constant solar irirradiation and, for various solar irirradiations with constant wind speed, the power flow of the hybrid power system is simulated and presented. The same topology is investigated for different switching frequencies (10 kHz and 20 kHz), using MATLAB/SIMULINK, and the efficiencies are calculated.
