Rapid population growth and industrialization in developing countries cause an increase in demand for energy. In order to meet this energy demand, two types of resources are used: renewable energy and nonrenewable energy. Nonrenewable sources, also called fossil fuels, cause environmental problems in serious and dangerous dimensions. For this reason, it is a necessity to find alternatives. It is a renewable energy source that can be used as an alternative to fossil fuels. This chapter deals with power control of a PV/wind system for power generation with dynamic input dataset. The main contribution of this chapter is that it is the first time to use real data from PV/wind system and observe the system reliability with real-time simulation results. The proposed system consists of doubly fed induction-based wind generator, rotor-side converter (RSC), grid-side converter (GSC), solar arrays, DC-DC converter and grid-side converter, and grid and dynamic loads. The aim of the proposed strategy is to use wind and solar energies with maximum efficiency by simulating the real condition of wind and insolation with input datasets. The modeling and the validation of the operation of the system and its controllers are done by using PSCAD/EMTDC.

The use of renewable energy sources has experienced great development so as to meet energy demand. With the intention of increasing the utilization of the renewable energy sources near the demand side and compensate the fluctuation of the output power, the use of micro-cogeneration systems with solar (PV) and wind energy overcomes both technical and economic barriers. Micro-cogeneration-based hybrid PV/wind energy system can get stable power output. This new energy model also improves the power quality and significantly reduces the impact of power instability on the power network. In this study, the grid-connected hybrid PV/wind energy-based micro-cogeneration system is modeled and analyzed in detail. In order to test the performance analysis of the system, seven different scenarios are analyzed during the case studies. The analysis results show that the new energy model presents effective solutions to electrical power balance because of its properties such as safety, incombustible structure, and being eco-friendly. It is aimed at providing a broad perspective on the status of optimum design and analysis for the micro-cogeneration-based hybrid PV/wind energy system to the researchers and the application engineers dealing with these issues.
