For medium-voltage (MV) high-power industrial applications including HVDC and variable-speed motor drives, multilevel converters are deemed predominant topology. One of the promising derived-topologies from neutral-point-clamped (NPC) configuration is active NPC (ANPC) inverter that offers improved characteristics. This paper proposes an improved ANPC (I-ANPC) converter controlled with an innovative logic-equation-based modulation method. The I-ANPC converter phase leg is realized by the cascaded connection of the single ANPC converter and one H-bridge cell. The H-bridge converter is formed by one flying-capacitor (FC) and four switches such as the insulated-gate bipolar transistors (IGBTs). The I-ANPC converter has considerable advantages over the classic multilevel inverters that makes it a preferable topology for MV applications. The substantial reduction in the number of cells in comparison with classic ANPC converter along with a drastic decrease in the total voltage rating and the stored energy of the capacitors are the main advantages offered by the I-ANPC multilevel converter over the FC-based inverters. This study explores the fundamental circuit of the proposed I-ANPC multilevel and its derived innovative logic-equation-based modulation technique, and provides an exhaustive comparison with FC-based classic converters. The simulation and experimental results are presented to validate the proposed I-ANPC topology and its logic-equation-based control strategy.

This paper presents a technique, implemented in an EMT type software, utilizing multiple cores of a processor, to simulate a single interconnected electrical power system. In this technique, large networks are split into smaller ‘subsystems’ by using the natural propagation delay introduced by transmission lines. This method does not introduce time step delays between subsystem solutions and hence yields computational results perfectly in agreement with the traditional non-split simulations. Proprietary and confidentiality issues arising from different vendors collaborating on large scale power system studies can also be resolved using the proposed technique.

This article presents an active disturbance rejection control (ADRC) scheme for the regulation of the angular position of the permanent magnet synchronous motor including physical implementation. The information of the angular position variable is provided by a classical resolver included in the motor. A high gain generalized proportional integral (GPI) observer-based active disturbance rejection controller is used for the unknown load torque. The only information needed for the control the motor is the angular position and the control gains. The design is robust with respect to the effects of the total disturbance. This includes: the input load torque, state dependent nonlinearities and un-modeled dynamics. Their combined effect is estimated trough a GPI observer. The ADRC is implemented using the a-b nonlinear model of the PMSM. Realistic co-simulation in Matlab/Simulink and Psim package, including realistic measurement disturbances, are used to investigate the stability and accuracy of the proposed control algorithm. The simulation results are then compared with laboratory experiments carried out on a surface-mounted permanent magnet motor using a dSPACE controller card.

This paper presents a distributed simulation based method for harmonic resonance assessment (HRA) in multi-area large-scale power systems. Further consideration is devoted to the early harmonic frequency-scan formulation to shape them into a Bordered Blocked Diagonal Form (BBDF), which is suitable for parallel processing. The proposed algorithm (BBDF) allows operator of each area of an interconnected system to independently conduct the HRA. A large-change sensitivity based approach is then handled in a secure platform to apply the effects of whole network to each single area. The introduced decentralized HRA is capable to find the exact values as those of the interconnected system through TCP/IP communication media. The developed method is successfully implemented in an existing software package and applied to IEEE 14-bus harmonic test system, followed by a discussion on results.

Fast switching of SiC MOSFETs in high frequency converters can be realized with an optimized gate driver. IXYS IXDD614 high-speed gate drivers can be used to deliver a source and sink peak current of 14A with gate voltage rise and fall times of less than 30ns to drive six paralleled 1.2kV 36A SiC MOSFETs. In this paper, a reliable and efficient gate driver is designed, evaluated, and experimentally validated to provide sufficient gate current for minimum on-resistance, fast switching operation, good noise immunity, and wide range of duty cycles and switching frequencies without significant self-heating. Also, the effect of the gate resistance on the gate driver performance is examined for different frequencies. The parasitic inductance values of the copper traces are analyzed using ANSYS Q3D Extractor. The designed gate driver without bootstrap capacitance can drive either the top or bottom switches of the six paralleled 1.2kV 36A SiC MOSFETs H-bridge converter module.

Power distribution systems are developing continuously and, consequently, the available short-circuit levels may exceed the ratings of the switchgear. One of the efficient methods of alleviating short-circuit currents is the reconfiguration. Network reconfiguration refers to the opening and closing of switches in a distribution system so that the network topology and, consequently, power flow from the substation to the consumers are changed. Distribution feeder reconfiguration (DFR) is a complex nonlinear combinatorial problem since the status of the switches is non-differentiable. This paper presents a new efficient algorithm for DFR, based on particle swarm optimization (PSO) algorithm, in order to minimize the short-circuit level. The numerical results of the proposed algorithm tested on the IEEE 83-Bus distribution system model reveals the feasibility, authenticity, and efficiency of the proposed PSO-based optimal reconfiguration algorithm.

This paper proposes an error minimization technique based active power management solution for net-load ramp rate control using integrated energy storage systems in a power distribution system. The proposed approach locally control the net-load ramp rate with an intention to minimize the timing imbalance of load peak and Photo-Voltaic (PV) generation at the distributed PV farms. The cumulative effect of such control with multiple energy storage is the overall reduction in the risk of over-generation in conventional generation units due to Behind-The-Meter (BTM) distributed PV farms. Methodology is applied on 4000 nodes non-aggregated model of distribution feeder in North Carolina. Results showed successful co-ordination between net-load control and other required applications. Energy storage system sizing trade-off is also discussed.

Energy storage systems (ESS) increase the flexibility of electric power systems and provide services and benefits to industry stakeholders. Optimization models are required to analyze these services in terms of their economic benefits to industry actors. Most of the existing research on ESS services has been for utility-owned ESS. On the other hand, privately-owned ESS benefits, an important emerging market, is not well-understood. This paper analyzes four of the most important ESS services and develops optimization models that maximize the owner's revenue for a single service and for multiple combined services. Simulation results with the California ISO market data show that the highest single-service revenue stream is the frequency regulation in this market. Also, multiple services are stacked to maximize the owner's revenue. When all the services are provided, ESS owner collects the highest revenue that is almost 80% of the sum of individual service revenues.

This note deals with the angular speed synchronization of two brushed DC motors coupled to a mechanism in order to drive collaboratively a common stiff shaft. The proposed control schema uses a decentralized active disturbance rejection (ADR) speed-tracking controller, which is based on the differential flatness property and on the design of two linear extended state observers. With the proposed collaborative control the total torque load shared by the motors as well as the couple load imposed by each motor is actively estimated and rejected in order to accomplish the control objective. The decentralized active disturbance rejection tracking controller algorithm is implemented in Real-Time using the TMS320F28335 DSP board. The results show an excellent performance in the transient and steady state for the angular speed tracking, even when the load in the common stiff shaft changes suddenly.

In this paper, a seamless transfer control strategy or algorithm for single phase grid-tied inverter is proposed using synchronous frame PLL. The inverter is controlled using the Direct-Quadrature synchronous reference frame transformation for active and reactive power control in the grid connected mode and output voltage control in the islanded mode of operation. The breaker status is responsible for the switching between the two control modes and the breaker status is decided by the proposed algorithm. The seamless transfer algorithm observes the PCC voltage on the grid side and the frequency of the grid and decides an action based on the whether the two parameters are within a particular limit. The SF-PLL is responsible for the synchronization process, it takes the reference from the grid or from a constant d-q component of the voltage depending on the output setting of the algorithm. The output of the SF-PLL will determine the frequency and phase angle of the inverter. Simulations verify the operation of this algorithm and the control modes used on the single phase inverter.
