A Unified Control and Power Management Schemefor PV-Battery-Based Hybrid Microgrids for Both Grid-Connected and Islanded Modes

ABSTRACT:  

Battery storage is usually employed in Photovoltaic (PV) system to mitigate the power fluctuations due to the characteristics of PV panels and solar irradiance. Control schemes for PV-battery systems must be able to stabilize the bus voltages as well as to control the power flows flexibly. This paper proposes a comprehensive control and power management system (CAPMS) for PV-battery-based hybrid microgrids with both AC and DC buses, for both grid-connected and islanded modes.

The proposed CAPMS is successful in regulating the DC and AC bus voltages and frequency stably, controlling the voltage and power of each unit flexibly, and balancing the power flows in the systems automatically under different operating circumstances, regardless of disturbances from switching operating modes, fluctuations of irradiance and temperature, and change of loads. Both simulation and experimental case studies are carried out to verify the performance of the proposed method.

CONCLUSION:

 This paper proposes a control and power management system (CAPMS) for hybrid PV-battery systems with both DC and AC buses and loads, in both grid-connected and islanded modes. The presented CAPMS is able to manage the power flows in the converters of all units flexibly and effectively, and ultimately to realize the power balance between the hybrid microgrid system and the grid.

Furthermore, CAPMS ensures a reliable power supply to the system when PV power fluctuates due to unstable irradiance or when the PV array is shut down due to faults. DC and AC buses are under full control by the CAPMS in both grid-connected and islanded modes, providing a stable voltage environment for electrical loads even during transitions between these two modes. This also allows additional loads to access the system without extra converters, reducing operation and control costs. Numerous simulation and experimental case studies are carried out in Section IV that verifies the satisfactory performance of the proposed CAPMS.

Three-Phase Unidirectional Rectifiers with Open-End Source and Cascaded Floating Capacitor H-Bridges

ABSTRACT

This paper presents two typologies of three-phase semi controlled rectifiers suitable for open-end ac power sources. The rectifiers are composed by a combination of two-level three phase bridges (controlled, semi controlled or uncontrolled), and three single-phase floating capacitor h-bridges (controlled). These typologies generate two powered dc-links, each one belonging to a three-phase bridge. They present a reduced number of controlled power switches if compared to other open-end configurations of similar complexity found in the literature.

S V P WM

It is also proposed a space-vector pulse width modulation (S V P WM) approach and a method of floating capacitor voltage control dedicated to the typologies, with an equivalent approach based on the level-shifted P WM (LS-P WM). The proposed S V P WM solving method is based on a redundant state selection (RS S) technique, which allows the floating capacitors voltage regulation. On the other hand, the LS-P WM solving method is based on the neutral voltage selection, which is shown to be equivalent to the S V P WM RS S technique seen from the control system. Simulation results are shown to validate proposed typologies, as well as the S V-P WM and LS-P WM techniques, and the control strategy. Experimental results are shown to demonstrate proposed configurations feasibility.

CONCLUSION

In this paper, two configurations of unidirectional rectifiers were proposed. They were based on the cascaded connection of two three-phase bridges with three floating capacitor h bridges (one per-phase), which was allowed by the open-end configuration of the three-phase power source. The voltage regulation of the floating capacitor h-bridges was realized by two proposed PWM solving techniques. The first was applied to the SV-PWM, where methods for redundancy selection and state switching minimization were also proposed. The second was proposed for the LS-PWM as an alternative to the SVPWM.

L S P WM

In this case, the floating capacitors voltage regulation was based in solving the P WM for appropriately selected neutral voltage references. Simulation results were provided to supply evidence that proposed typologies are viable and that proposed S V-P WM redundancy selection technique is effective within the control system. It was also shown that the control based on the LS-P WM was effective and equivalent to the S V-P WM. It could be concluded that the proposed configurations could present lower current TH D and voltage W TH D with fixed switching frequency, as well as lower semiconductor losses with matched current TH D, if compared to the conventional three-phase I B GT rectifier bridge. Simulation results also provided to show the feasibility of proposed typologies and control strategy.

ABSTRACT:

Because of its high vitality age ability and negligible natural effect, wind vitality is an exquisite answer for the developing worldwide vitality request. In any case, visit environmental changes make it hard to adequately bridle the vitality in the breeze since greatest power extraction happens at an alternate working point for each wind condition. This paper proposes a parameter autonomous astute power the executives controller that comprises of an incline helped most extreme power point following (MPPT) calculation and a power limit look (PLS) calculation for little independent breeze vitality frameworks with perpetual synchronous generators. Dissimilar to the parameter free irritate and watch (P&O) calculations, the proposed incline helped MPPT calculation appropriates consistent blunders credited to twist vacillations by distinguishing and recognizing air changes. The controller’s PLS can limit the generation of surplus vitality to limit the warmth scattering prerequisites of the vitality discharge instrument by collaborating with the state spectator and utilizing the slant parameter to look for the working focuses that outcome in the ideal power instead of the greatest power. The usefulness of the proposed vitality the executives control conspire for wind vitality frameworks is confirmed through reproduction results and exploratory outcomes.

Fig 5 Power coefficient performance of the fixed-step size P&O, variable step size P&O, and the slope assist MPPT (comparison performed under atmospheric identical conditions as depicted in Fig.20).

CONCLUSION:

In this paper, a keen parameter-autonomous power the executives controller has been displayed for independent offgrid little wind vitality frameworks. With the state eyewitness directing the incline helped MPPT and the PLS in the proposed controller, the union occasions to the ideal working focuses is decreased and the legitimate mistakes are limited by distinguishing the adjustments in wind conditions. Being pertinent for both matrix associated and independent breeze frameworks, the slant help MPPT expands a breeze framework’s MPP seek effectiveness and empowers the breeze framework to effectively adjust to its changing conduct and wind conditions. The PLS calculation was intended to supplement the slant help MPPT for independent breeze frameworks that have restricted vitality stockpiling and use vitality dissemination systems to scatter surplus vitality. Instead of concentrating on catching greatest power, as far as possible inquiry centers around decreasing the size and warmth necessities of the vitality dissemination component by limiting surplus power age as wanted. The working standards of the proposed PLS and MPPT control systems have been talked about in this paper. Reproduction results on a 3kW framework and test results on a proof-of-idea model with a breeze turbine emulator have been given to feature the benefits of this work.

POWER ELECTRONICS PROJECTS

Power electronics is the technology associated with the efficient conversion, control and conditioning of electric power by static means from its available input form into the desired electrical output form.

Power electronic converters can be found wherever there is a need to modify the electrical energy form (i.e. modify its voltage, current or frequency.) With “classical” electronics, electrical currents and voltage are used to carry information, whereas with power electronics, they carry power. Some examples of uses for power electronic systems are DC/DC converters used in many mobile devices, such as cell phones or PDAs, and AC/DC converters in computers and televisions. Large scale power electronics are used to control hundreds of megawatt of power flow across our nation.

POWER SYSTEMS:

Electric power systems are comprised of components that produce electrical energy and transmit this energy to consumers. A modern electric power system has mainly six main components: 1) power plants which generate electric power, 2) transformers which raise or lower the voltages as needed, 3) transmission lines to carry power, 4) substations at which the voltage is stepped down for carrying power over the distribution lines, 5) distribution lines, and 6) distribution transformers which lower the voltage to the level needed for the consumer equipment. The production and transmission of electricity is relatively efficient and inexpensive, although unlike other forms of energy, electricity is not easily stored, and thus, must be produced based on the demand.

It enables us to display very easily results on graphs and images. To get started with it, you need to understand how to manipulate and represent data, how to find information about the available functions and how to create scripts and functions to generate programs. This course is designed for comprehensive coverage of Matlab from down-to-the-earth level.
