Book Optimal Control of Renewable Energy grid Hybrid Systems with Heat Pump Load

Download or read book Optimal Control of Renewable Energy grid Hybrid Systems with Heat Pump Load written by Sam M. Sichilalu and published by . This book was released on 2016 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rising costs, power deficit and environmental concerns about fossil fuel-based energy resources have led to significant research effort in renewable and cleaner energy resources. Globally, governments are adopting policies to promote the development and application of various renewable energy (RE) technologies for generating electricity. The main challenge associated with RE technologies such as solar and wind generation is their intermittent nature, which affects their ability to provide 100% supply reliability. Combining these RE sources with energy storage systems such as battery storage and hydrogen can be cost-effective. Currently there are limitations to the fraction of RE that can be incorporated in the grid system because of their intermittency and base load considerations. The major challenge is the escalating power demand, far above the installed capacity in most countries. This requires urgent mitigation of demand side management(DSM), in order to stabilize the imbalance in the short, medium and long term. Energy efficiency and optimal integration could provide one of the most effective technological solutions, with the usage of energy-efficient devices such as heat pump water heaters (HPWH). These collective efforts at energy saving should involve proper selection of an appropriate technology, application of optimal control (OC) in RE, usage of energy-efficient equipment, green building materials and an effective energy policy. The proper integration of these sources and the use of HPWH could reduce the power utility?s maximum demand and improve the security of the supply. Most countries at policy level are beginning to introduce attractive feed-in tariffs, dynamic energy pricing (time-of-use) and rebate systems for using greener energy and energy-efficient load such as HPWHs. Hence, this thesis provides the first practical attempt to integrate various distributed energy resources (DRE) effectively into the grid, using HPWHs for the generation of the required thermal energy. This multi-directional approach in this work has proven that OC strategy could significantly reduce the cost of energy and provide an opportunity for power trade-off/feed-in in the electricity market. This thesis developed four main models that meet both the technical and operational constraints of DSM and optimal integration of DREs. Solar energy is abundant in Africa, its exploitation in addition to other REs is a priority in this work. The first model is an optimal scheduling strategy of a gridtied/ battery/PV system supplying HPWH. Secondly, an optimal energy management model with a diesel generator back-up system is developed that minimizes the fuel cost, while maximizing the utilization of renewable energy with a HPWH. Thirdly, in OC model of a HPWH, the thermal output is state variable. It is supplied by the second abundant wind energy hybrid resources. An economic analysis is done in this model to assess the break-even period, which is important to every investor. Finally, the future green energy hydrogen fuel cell hybrid system is modeled. Hydrogen has attracted attention in modern research owing to its ability to reduce carbon dioxide emissions, thus helping to mitigate climate change, improve local air quality, improve energy security by reducing energy imports, increase energy supply options and reduce dependence on fossil fuels. These models are suitable for application in both urban and rural areas where the electrical power power supply is intermittent. These models have several advantages for building owners intending to turn their dwelling into zero/positive energy buildings and enter electricity market. However, engineering solutions alone cannot yield much success on DSM, sensitization and education on energy savings at individual level and how these are intertwined with climate change are of the utmost importance.

Book Optimal Control Schemes for Power System with Unified Power Flow Controller UPFC

Download or read book Optimal Control Schemes for Power System with Unified Power Flow Controller UPFC written by Dr. Hidaia Mahmood Alassouli and published by Dr. Hidaia Mahmood Alassouli. This book was released on 2021-04-18 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: FACTS are one aspect of power electronics revolution that is taking place in all areas of electrical energy. A variable of powerful semiconductor devices not only offer the advantage of high speed and reliability of switching but, more importantly, the opportunity offered by a variety of innovative circuit concepts based on these power devices enhance the value of electric energy. In generation area, the potential application of power electronics is largely in renewable generation. Photovoltaic and fuel cells requires conversion of dc to ac. Generation with variable speed is necessary for economic viability of wind and small hydro generators. Variable-speed wind generators and small hydro generators requires conversion of variable frequency ac to power system frequency. These applications of power electronics in renewable generation area require converter sizes in the range of few kilowatts to few megawatts. In coming decades, electrical energy storage is expected to be widely used in power systems as capacitor, battery and superconducting magnet technologies move forward. Batteries are widely used already for emergency power supplies. These require ac/dc/ac converters in the range of a few kilowatts to a few tens of megawatts. On the other hand, variable speed hydro storage requires converters of up to a few hundred megawatts. In transmission area, application of power electronics consists of High Voltage Direct Current (HVDC) power transmission and FACTS. HVDC is often an economical way to interconnect certain power systems, which are suited in different regions separated by long distances or those have different frequencies or incompatible frequency control. HVDC involves conversion of ac to dc at one end and conversion of dc to ac at the other end. What is most interesting for transmission planners is that FACTS opens up new opportunities for controlling power and enhancing the usable capacity of the lines. The possibility that current through a line can be controlled at reasonable cost enables a large potential of increasing the capacity of the existing lines with larger conductors, and use one of the FACTS controllers to enable corresponding power to flow through lines under normal and contingency conditions. These opportunities arise through the ability of FACTS controllers to control the interrelated parameters that govern the operation of transmission line including series impedance, shunt impedance, current, voltage, phase angle, and the damping of oscillations at various frequencies below the rated frequency. In distribution area, an exciting opportunity called Custom Power. The custom power concept incorporates power electronics controllers and switching equipment, one or more of which can be used to provide a value-added service to the customers. In general, these custom service applications represent power electronics in the range of few tens of kilowatts to few ten of megawatts of conversion or switching equipment between the utility supply and customer. On the end-user side, power electronics conversion and switching technology has been fast growing area. Complementing the Custom Power technology is the whole area of power conditioning technology used by customers, under the term Power Quality. Uninterruptible power supplies (UPS) and voltage regulators represent the major growth area in power electronics. In end use, the converter sizes range from a few watts to ten of megawatts. The term active filter is a general one and is applied to a group of power electronic circuits incorporating power switching devices and passive energy storage circuit elements such as inductors and capacitors. The functions of these circuits vary depending on the applications. They are generally used for controlling current harmonics in supply networks at the low and medium voltage distribution level or for reactive power and/or voltage control at high voltage distribution level. These functions may be combined in a single circuit or in separate active filters. Most of the control schemes introduced in the existing papers were designed either for eliminating current harmonics or eliminating voltage flickers or for load flow control. So, this work is devoted to find a proper optimal control schemes for a system with series or shunt or series and shunt converters that can provide all functions together. Various optimal control schemes will be designed for systems with series, shunt and series-shunt converters with the objective to control the load flow through a lines and to eliminate current harmonics and voltage flickers with different strategies for tracking. · Part 1: Gives the description of optimal control design. · Part 2: Case studies to design different optimal control schemes for system with UPFC unit to control the power flow, eliminate voltage flicker and eliminate current harmonics. The case studies were repeated for system with only series or shunt converters.
