Latterly, impedance source based multilevel inverters are becoming popular for emerging renewable power generations. This paper presents a Five-Level quasi Z-source (qZS) based neutral point clamped (NPC) for photovoltaic (PV) applications. This inverter circuit is formed by integrating a dual quasi Z-source with a T-type arm and a diode clamped arm. Compared to the existing impedance source based NPC type converters, the proposed topology has less number of switching devices and reduced voltage stress. The level shifted pulse width modulation (LS-PWM) with hybrid shoot-through technique is implemented to achieve high boost gain and reactive power capability. The performance of the proposed topology is examined through simulation results for input voltage changes and load changes.

This paper presents a cost-benefit analysis of using battery storage to provide energy during the peak period of a substation transformer, rated 300-MVA, 230/121-22 kV. The battery sizing is optimized by varying the target power of peak shaving. Although the investment cost of battery is very high, but the benefits from price arbitrage and loss reduction are financially attractive. Thus, using battery storage for peak shaving is viable, but may not be profitable. The breakeven point is then determined to justify the investment.

This paper presents an asset planning approach for managing a primary power supply equipment from economical point of view. The technical and economic analyses are illustrated through a case study comparing two options applicable for an aged power transformer, replacement versus complete overhauling. Initial investment, cost of overhauling, and operation and maintenance are the main inputs to the developed economic model.

This paper proposes an online fault localization technique for line commutated converter high voltage direct current (LCC-HVDC) transmission links, which use single core monopolar cables with metallic return. The conducting layers of the cables have mutual off-diagonal elements in the longitudinal impedance matrix. Thereupon, in case of faults in DC transmission section due to the coupling between conducting layers, using the direct measurements for localizing the fault results in a noticeable amount of error. In this paper, based on the modal theory, the longitudinal matrix of HVDC cable bundle is diag-onalized into the decoupled modal matrix. Each of the resulted modes has different attenuation, velocities, and characteristic impedances. According to this velocity difference, an online one-sided modal fault location algorithm is presented. The proposed method gives more accurate results than common methods that use direct traveling wave data for fault localization. Discrete Wavelet Transform (DWT) is used for detecting modal initial peaks. CIGRE LCC-HVDC link is modeled in PSCAD/EMTDC and further fault location algorithm is designed in MATLAB. The comparison between obtained results and techniques based on direct measurement proves the accuracy and robustness of the proposed modal fault location algorithm.

The negative impedance characteristics of constant power loads (CPLs) and transient recovery stresses after fault isolation can cause system transient instability, load shedding and the possibility of load detriment in a microgrid if the conventional linear controllers are employed. With the complexity in the power distribution and the renewable integration, there is a need for an effective controlling technique with the attributes of the conventional controller; transient mitigating capability. This paper formulates a nonlinear backstepping control for the power electronic interfaces of an islanded DC microgrid giving a transient stability analysis for different contingencies incurring the system. The designed controller performance is validated using MATLAB/SIMULINK.

This work presents an analysis of two techniques used to analyze the frequency domain characteristics of conducted emissions measured in time domain using a LISN connected to two Switched-Mode Power Supplies. The considered interval is 10-150 kHz. The two techniques are the Short Time Fourier Transform and the Empirical Mode Decomposition method, focusing on spectral properties of impulsive phenomena, and compatibility with the typical settings of EMI receiver, whose output represents a validation reference case. The analysis points out the influence of the record length and resolution bandwidth with respect to the local signal non-stationarity.

Primary regulation of islanded Microgrids is one of the most relevant topics in an academic and industrial world. IEEE Std 1547-2018 defines the functionalities of GridSupporting inverters and one of the control goals is the correct reactive power sharing. This paper focuses the attention on the performance of the conventional droop technique in the control of reactive power flows and voltage. After defining the MG structure, a detailed mathematical model for the study of the problem is presented in order to carry out a MG parameters and a regulators parameters sensitivity analysis.

EU Network Codes are encouraging power system operators to integrate nonconventional generation units in the evolving Ancillary Services Markets. Article 156 of System Operation Guidelines requests TSOs to perform a cost-benefit analysis for defining a minimum delivery time period for Frequency Containment Reserve (FCR) provided by units with Limited Energy Reservoirs (LER). A research group in Politecnico di Milano followed the process closely cooperating with ARERA, the Italian Regulatory Authority. This paper aims at describing in depth the methodology proposed by TSOs for analyzing system costs related to the introduction of a certain share of LER among FCR providers. Some qualitative and quantitative investigations are then proposed. Critical aspects of the methodology proposed by TSOs are described. The impact on energy storage of the differences among countries’ way of providing FCR is highlighted.

Mass adoption of Electric Vehicles (EVs) will bring some challenges to the operators of electric utilities. This paper proposes a decentralized control algorithm to manage the charging of distributed EVs. The proposed algorithm is inspired by the Additive Increase - Multiplicative Decrease (AIMD) algorithm, which is commonly used for the management of communication network congestions. The improved algorithm takes into consideration the preferences of the owners of the EVs. Also, it eliminates the overloading and the under-voltage problems that might be associated with the charging of EVs. The proposed algorithm is validated using a co-simulation platform, where the power components are simulated using MATLAB/Simulink and is linked to embedded microcontrollers over a real-time communication network via the Data Distribution System (DDS) middleware.
