Abstract
The aim of the paper is the study of the Hybrid Renewable Energy System, which is consisted of two types of renewable energy systems (wind and sun) and is combined with storage energy system (battery). The paper presents the classification and review of architectures of Hybrid Renewable Energy Systems. The considered Hybrid Renewable Energy System was designed as a multi-converter system with gearless Wind Turbine driven Permanent Magnet Synchronous Generator and with a Photovoltaic Array and Battery Energy System. The mathematical models of individual elements of a complex Hybrid Renewable Energy System were described. In the control of both systems of Wind Turbine with Permanent Magnet Synchronous Generator and Photovoltaic array, the algorithms of Maximum Power Point Tracking have been implemented for higher efficiency of energy conversion. The energy storage in the battery has been managed by the control system of a bidirectional DC/DC converter. For the control of the Machine Side Converter and Wind Turbine with Permanent Magnet Synchronous Generator, the vector control method has been implemented. In the control system of the Grid Side Converter, the advanced method of Direct Power Control has been applied. The energy management strategies for optimal flows of electrical energy between individual systems of considered hybrid renewable energy system are developed and described. In order to determine the operation of proposed control systems, the simulation studies have been performed for different conditions of operation of individual elements of the complex hybrid system. The considered control methods and energy management strategies were tested thorough simulation studies for different wind speed variations, different sun irradiations, and different local load demands. The performed simulations are of practical importance in terms of proper operation requirements, design selection of components and energy management of Hybrid Renewable Energy Systems.

Summary
The penetration of renewable energy resources in power systems is increasing rapidly, especially for Wind Energy Conversion Systems (WECS) and Photovoltaic Systems (PV) [1,2]. Hybrid Renewable Energy Systems are becoming popular for power generation applications due to advances in renewable energy technologies These systems are attractive because the individual sources could complement one another to provide more reliable power to the customer than a single-source system. In order to ensure the better conditions for continuity of power delivery to the local loads, it is essential to make WECS and PV systems compatible with additional energy storage systems [3,4]. In this case, the battery bank, flywheel, super capacitor, or fuel cell may be used as the energy storage devices [5]
