An increase in interconnection of power systems may lead to poor damping oscillation. This paper studies the oscillation damping performance of the Power System Stabilizer (PSS) and Power Oscillation Damper which are located on a photovoltaic plant (PV-POD). A computer simulation of a power system with PSS and PV-POD is conducted in Matlab/Simscape Power System. The study consists of five scenarios with different operating conditions. To compare the damping performance, the results from the Eigen analysis and time domain analysis from the computer simulation are used to analyze the damping quality. The results show that the oscillation damping obtained from the system with POD is better than that from the system with PSS. However, when the operating condition of the system is changed, the oscillation damping of the system with PSS is more consistent than that of the system with POD.
电力系统互连程度的增加可能导致阻尼振荡不良。本文研究了安装在光伏电站(PV-POD)上的电力系统稳定器(PSS)和电力系统振动阻尼器(PSS)的减振性能。在Matlab/Simscape电力系统中对PSS和PV-POD组合的电力系统进行了计算机仿真。该研究包括五个不同操作条件的场景。为了比较阻尼性能,利用计算机仿真的本征分析和时域分析结果对阻尼质量进行了分析。结果表明,采用POD系统的振动阻尼优于采用PSS系统的振动阻尼。然而,当系统运行条件发生变化时,PSS系统的振荡阻尼比POD系统的振荡阻尼更一致。

This paper proposes a calculation method to determine the frequency deviation of microgrid (MG) system in transferring mode, using the mathematical model of distribution slack bus load flow (DSLF). In the proposed method, the modified incorporating Newton-Raphson load flow incorporating generation control equations are used to find the primary frequency deviation. The IEEE radian distribution 33-bus was modified as an microgrid model and used to test the proposed method.

In this paper, the output DC bus voltage stabilization and the current sharing of a multi-phase parallel interleaved FC boost converter is presented. The proposed robust controller by adding an integrator action is based on the Hamiltonian–Lyapunov function. The effectiveness and robustness of the designed controller have been successfully authenticated by experimental results obtained using a 2.5-W prototype FC converter (by four-phase parallel interleaved boost converters) and a dSPACE MicroLabBox platform. The FC main source system is based on a fuel reformer engine that converts fuel methanol and water into hydrogen gas H2 to a polymer electrolyte membrane FC stack (50–V, 2.5–kW).

Battery Management System (BMS) is a critical component in modern electrical technology. The exact knowledge of the state of health and capacity impact is useful for the estimation and control strategy of battery. Therefore, this paper proposed the particle swarm optimization-based Feedforward Neural Network (PSO-FNN) for Battery Aging Estimate (BAE). This PSO is used to optimize the weights and biases of the FNN. For validating the proposed method, conventional FNN was simulated with battery data sets provided by NASA Prognostics Center of Excellence (PCoE) and compared to the proposed method. The simulation results show the performance of PSO-FNN is noticeably better in relatively volatile systems.

In this paper, we present an adaptive averaging step-size inverse square-root affine projection sign algorithm. Based on the QR-decomposition method, we derive the modified inverse autocorrelation matrix in order to reduce the complexity of inverse matrix, which a criterion is based on the proposed algorithm with the sign error. Adaptive averaging step-size mechanism is used for the fast adaptation. Convergence analysis in form of a posteriori error is presented. Simulation results show that the proposed algorithm can obtain clearly the better performance compared with the conventional affine projection algorithm.

This paper proposes the electromagnetic band gap (EBG) reflector using split ring resonator with interdigital technique. The capacitive value between split ring gaps has the results of slow-wave effect in transmission line, that can reduce the size of split ring resonator unit cell from λ/2 to about λ/4. Moreover, it can control the second harmonics to resonance at the required frequency for the second band operation. The unit cell will be designed at the fundamental frequency of 1.8 GHz and the second resonance frequency of 2.4 GHZ, which are the frequency bands of LTE and WLAN systems. The unit cells are arranged in an array to act as a reflector for a dipole antenna. The simulation results at both operating frequency bands show the antenna gains of 8.17 dB and 8.29 dB at 1.8 GHz (460 MHz bandwidth) and 2.4 GHz (470 MHz bandwidth), respectively.

The conventional Medium voltage (MV) and Low Voltage (LV) distribution power network had the power flow in one direction, which flows from the power plant (calls central generating) downward to the consumer. However, this power flow direction is starting to change, and hence it is becoming the Bi-directional. Because the accommodating of Renewable Energy resources (REs) such as wind turbine, Photovoltaic (PV) and Electric Vehicles (EVs) etc. In addition, the uses of power electronic devices such as converter (stabilises the use of voltage), inverter (inverses between AC-DC or DC-AC) and charger (supports EVs) are also dramatically increasing, and thus it is also effected the Power Quality (PQ) on the distribution network as same as the power flow. According to the impacts of the REs and EVs, the distribution network must face the challenge. The demand of electricity such as the consumers' behavior, types of REs, charging/un-charging EVs is necessary to investigate. This investigation will be more complicated as the variations in demand profiles. These large data in the network can be called the ‘Big data' of the power network. The ‘Big data' can increase the development in the monitoring and controlling systems of the network, and hence it is allowed the network to become smart network. The distribution network must have the ability and capability to accommodate the REs and EVs. Therefore, the standards and regulations of REs and EVs connection, standards and regulations of Feed-In-Tariffs (FIT), the revision of Power Purchase Agreement (PPA) between provider and consumer, smart meters, smart On-Load Tap Changer Transformer (OLTC), smart EVs Car Park, Smart Energy Storage, smart Artificial Intelligent (AI) to manage Big Data, etc. are necessary required to study.
传统的中压(MV)和低压(LV)配电网的潮流是单向的,即从发电厂(称为集中发电)向下流向用户。然而,这种能量流动的方向正在开始改变,因此它正在成为双向。由于可再生能源(REs)如风力涡轮机,光伏(PV)和电动汽车(ev)等的容纳。此外,变流器(稳定电压的使用)、逆变器(交直流或直流-交流之间的逆变器)和充电器(支持电动汽车)等电力电子设备的使用也急剧增加,从而在影响潮流的同时也影响了配电网的电能质量(PQ)。由于可再生能源和电动汽车的冲击,配电网必须面对挑战。对消费者行为、可再生能源类型、充电/不充电电动汽车等电力需求进行调查是必要的。随着需求概况的变化,这项调查将更加复杂。这些网络中的大数据可以被称为电网的“大数据”。“大数据”可以促进网络监控系统的发展,从而使网络成为智能网络。配电网必须具备适应可再生能源和电动汽车的能力。因此,可再生能源与电动汽车连接的标准法规、上网电价(FIT)的标准法规、购电协议(PPA)的修订、智能电表、智能有载分接变压器(OLTC)、智能电动汽车停车场、智能储能、智能人工智能(AI)管理大数据等都是需要研究的。

However, this power flow direction is starting to change, and hence it is becoming the Bi-directional. Because the accommodating of Renewable Energy resources (REs) such as wind turbine, Photovoltaic (PV) and Electric Vehicles (EVs) etc. In addition, the uses of power electronic devices such as converter (stabilises the use of voltage), inverter (inverses between AC-DC or DC-AC) and charger (supports EVs) are also dramatically increasing, and thus it is also effected the Power Quality (PQ) on the distribution network as same as the power flow. According to the impacts of the REs and EVs, the distribution network must face the challenge. The demand of electricity such as the consumers' behavior, types of REs, charging/un-charging EVs is necessary to investigate.
