The main objective of this work is to design and simulation of the stand-alone Hybrid Renewable Energy system (HRES), separated from the main local network, the effect of super capacitors when connected to the system, and the effect of power source control system on the response and work of super capacitors. It consists of Photovoltaic, Wind turbine, Hybrid Energy Storage System (HESS). The HESS system consist of Batteries, Supper capacitors, with chargers. The proposed system used real record of weather pattern and load conditions for Al-Mahmoudiya Hospital. The variable sources are changing with different weather conditions. Being important energy sources for generating electricity directly from the sun. In order to generate electrical energy that is sustainable and reliable, highly efficient, low cost, and continuous. It can provide maximum power use. The absence of winds in most regions of Iraq permanently led to the use of such a type of renewable energy (RE) system called solar updraft tower (SUT). The wind turbine can be fixed inside the chimney of the SUT, to make the turbine run smoothly and continuously. Each of the HRES parts is controlled by a converter specific to each source due to the nature of the nonlinear source work. In this paper, the main sources of energy are photovoltaic panels and SUT. Finally, MATLAB program using real recorded data, the system work at a high efficiency of 98%. So the simulation results show the HRES system have excellent results and fast tracking to supply the load demand.

Hybrid Renewable Energy

To reduce carbon and greenhouse gas emissions, the more efficient and environmentally friendly energy production in the building sector is required. The deployment of renewable energy based microcogeneration units in the decentralized hybrid energy systems is a part of the solution. The micro combined heat and power (micro-CHP), or co-generation, units produce simultaneously heat and electricity from a single fuel source at high efficiency and close to the consumption point. These units offer significant benefits: reduced primary energy consumption, reduced CO2 emissions, and avoidance of distribution losses due to central plant and network construction. The objective of this paper is to present a review of available renewable energy based micro-CHP systems and to focus on the biomass and solar based conversion devices. Finally, a novel hybrid renewable energy system is presented by coupling renewable energy sources, such as solar and biomass for micro-CHP.

It is very important that the installed renewable energy system should produce the maximum power outputs with minimum costs, and that can only be achieved with the selection of the best optimization technique applied for the best control strategies along with the introduction of the hybrid energy storage systems (HESS). This chapter presents some optimization techniques applied in control strategies for hybrid energy storage systems in distributed renewable energy systems. The integration of energy production and consumption component through the smart grid concept enables increased demand response and energy efficiency. Hybrid energy storage systems and their applications in the renewable energy systems are extensively discussed besides control strategies involved. The storages systems will play an important role in future related to smart grid.

This paper proposes an enhanced energy management system (EEMS) for a residential AC microgrid. The renewable energy-based AC microgrid with hybrid energy storage is broken down into three distinct parts: a photovoltaic (PV) array as a green energy source, a battery (BT) and a supercapacitor (SC) as a hybrid energy storage system (HESS), and apartments and electric vehicles, given that the system is for residential areas. The developed EEMS ensures the optimal use of the PV arrays’ production, aiming to decrease electricity bills while reducing fast power changes in the battery, which increases the reliability of the system, since the battery undergoes fewer charging/discharging cycles. The proposed EEMS is a hybrid control strategy, which is composed of two stages: a state machine (SM) control to ensure the optimal operation of the battery, and an operating mode (OM) for the best operation of the SC. The obtained results show that the EEMS successfully involves SC during fast load and PV generation changes by decreasing the number of BT charging/discharging cycles, which significantly increases the system’s life span. Moreover, power loss is decreased during passing clouds phases by decreasing the power error between the extracted power by the sources and the required equivalent; the improvement in efficiency reaches 9.5%.
