ABSTRACT:

In this work, two real-time energy management strategies have been investigated for optimal current split between batteries and ultracapacitors (UCs) in electric vehicle (EV) applications. In the first strategy, an optimization problem is formulated and solved using Karush-Kuhn-Tucker (KKT) conditions to obtain the real-time operation points of current split for the hybrid energy storage system (HESS). In the second strategy, a neural network based strategy is implemented as an intelligent controller for the proposed system. To evaluate the performance of these two real-time strategies, a performance metric based on the battery state-of-health (SoH) is developed to reveal the relative impact of instantaneous battery currents on the battery degradation. A 38V-385Wh battery and a 32V-4.12Wh UC HESS hardware prototype has been developed and a real-time experimental platform has been built for energy management controller validation, using xPC Target and National Instrument data acquisition system (DAQ). Both the simulation and real-time experiment results have successfully validated the real-time implementation feasibility and effectiveness of the two real-time controller designs. It is shown that under a high speed, high acceleration, aggressive drive cycle US06, the two real-time energy management strategies can greatly reduce the battery peak current and consequently decreases the battery SoH reduction by 31% and 38% in comparison to a battery-only energy storage system.

INTRODUCTION:

          Electric vehicles (EVs) face significant energy storage related challenges, including the range anxiety, high cost, and battery degradation. Batteries, as the energy storage components in majority of current and upcoming EVs, deliver energy to the electric machine during propulsion and recover energy during regenerative braking. For urban drive cycles with frequent stop-and-go, the frequent high power exchange between the electric machine and the ESS results in accelerated battery aging. The battery aging decreases the battery capability of storing energy and providing power over the battery lifetime. One potential solution to this problem is to integrate high-energy (HE) density batteries with high-power (HP) density ultracapacitors (UCs) as hybrid energy storage systems (HESS). UCs has complementary features to batteries with fast charge-discharge, excellent power performance over broad temperature range, long lifetime and high reliability. UCs can protect batteries against fast charging/discharging, reduce high peak power and relieve the battery thermal burden; therefore, prolong the battery lifetime.

 

PROPOSED SYSTEM:

          In this work, two real-time energy management strategies have been investigated for optimal current split between batteries and ultracapacitors (UCs) in electric vehicle (EV) applications. In this work, the semi-active HESS topology is considered. With this topology, the UC pack discharging/charging current Iuc can be controlled through the control of the DC-DC converter. In addition, as the UC pack is decoupled from the dc bus, its voltage can be lower than the dc bus voltage, and consequently the size and cost of UC can be reduced.

APPLICATIONS:

  • Electric vehicles (EVs).

Control and Implementation of a Standalone Solar Photo-Voltaic Hybrid System

Control and Implementation of a Standalone Solar Photo-Voltaic Hybrid System

Control and Implementation of a Standalone Solar Photo-Voltaic Hybrid System

ABSTRACT:

A control algorithm for a standalone solar photovoltaic (PV)-diesel-battery hybrid system is implemented in this paper. The proposed system deals with the intermittent nature of the energy generated by the PV array and it also provides power quality improvement. The PV array is integrated through a DC-DC boost converter and controlled using a maximum power point tracking (MPPT) algorithm to obtain the maximum power under varying operating conditions. The battery energy storage system (BESS) is integrated to the diesel engine generator (DG) set for the coordinated load management and power flow within the system. The admittance based control algorithm is used for load balancing, harmonics elimination and reactive power compensation under three phase four-wire linear and nonlinear loads. A four-leg voltage source converter (VSC) with BESS also provides neutral current compensation. The performance of proposed standalone hybrid system is studied under different loading conditions experimentally on a developed prototype of the system.

INTRODUCTION:

          Nowadays, the rapid increase in the use of nonlinear loads such as computers, electronics appliances, medical equipment, refrigerators etc. has emphasized the concern for power quality in the electrical distribution system. These loads inject harmonics and distort the current and voltage waveforms causing poor power quality problems. The possible provision for the mitigation of the power quality problems is with inclusion of custom power devices (CPDs). Three-phase four-wire loads are also known to suffer from the problem of neutral current due to non-linearity and unbalance present in the system. This may produce large amount of neutral current which consists of triplen harmonics. The neutral current may cause over-loading of the distribution system and causes additional heat losses which may be dangerous and poses a serious threat to the connected equipment. A four-leg VSC is used for neutral current compensation in addition to mitigate the current harmonics with other reported advantages.

 

PROPOSED SYSTEM:

          The standalone system consists of a PV array along with a boost converter, MPPT controller, diesel engine driven permanent magnet synchronous generator (PMSG), a four-leg VSC with BESS and three-phase four-wire AC loads. The voltage at the point of common coupling is restored by coordinating the reactive power through VSC control. Under varying conditions of generation and loads, BESS offers charging during the daytime when the insolation is large and the load is less. The battery discharges to compensate for any deficits. The DG set operates while maintaining the system frequency under varying generation and loads. The terminal capacitor provides a constant rated terminal voltage at no load. A four leg VSC is interfaced along with its DC bus. The ripple filter and interfacing inductors are used to eliminate the switching harmonics.

 812

ADVANTAGES:

  • Eliminate harmonics, load balancing.
  • Provide neutral current compensation by incorporating four-leg VSC.
  • The ripple filter and interfacing inductors are used to eliminate the switching harmonics.

  • Telecommunication systems.
  • Hospitals.

Isolated Double Step-down DC-DC Converter with Improved ZVS Range and No Transformer Saturation Problem

Isolated Double Step-down DC-DC Converter with Improved ZVS Range and No Transformer Saturation Problem

ABSTRACT:

In this paper, an isolated double step-down DC-DC converter with high efficiency and high step-down function is proposed. The proposed converter employs an additional capacitor in the primary side. Compared to the conventional full-bridge converters, the proposed converter has a double step-down feature with reduced voltage stress at the primary side of the transformer. Moreover, voltage stress of three primary side switches reduces to half of the input voltage and zero voltage switching (ZVS) is naturally achieved for all switches with lower output capacitor energy of the switches. Therefore, the proposed converter requires smaller leakage inductance than the conventional full-bridge converter. Without adding complexity to the hardware and control, the proposed converter inherently prevents transformer saturation problem caused by the DC component of the transformer. A 3-kW experimental prototype is constructed to verify the performance of the proposed converter.

 

INTRODUCTION:

          Nowadays, distributed power system (DPS) is extensively employed in industries, such as telecommunications, computer technology, and information technology, which require high quality and reliability. The DPS generally consists of a power factor correction (PFC) circuit and an isolated DC-DC converter. The DC-DC converter requires both isolation and high step-down conversion ratio from 400 V to 48 V.

PROPOSED SYSTEM:

          In this paper, an isolated double step-down DC-DC converter with high efficiency and high step-down function is proposed. The proposed converter employs an additional capacitor in the primary side.

          The proposed converter has a double step-down feature with reduced voltage stress at the primary side of the transformer. Moreover, voltage stress of three primary side switches reduces to half of the input voltage and zero voltage switching (ZVS) is naturally achieved for all switches with lower output capacitor energy of the switches. Therefore, the proposed converter requires smaller leakage inductance than the conventional full-bridge converter. Without adding complexity to the hardware and control, the proposed converter inherently prevents transformer saturation problem caused by the DC component of the transformer.

ADVANTAGES:

  • Double step-down function and reduced switch voltage stress.
  • Higher efficiency because the reduced voltage stress enables the proposed converter to operate at a wider ZVS range with reduced switching losses.
  • No transformer saturation problem even when a mismatch exists in the switch duty ratio.

APPLICATIONS:

  • Telecommunications.
  • Computer technology.
  • Information technology.
