A distributed secondary voltage controller is designed for droop-controlled microgrids in power distribution networks to improve power quality. Microgrids are typically managed by the droop control mechanism that ensures stability but does not guarantee power quality of voltage magnitude. To solve this power quality problem, the proposed distributed secondary voltage controller maintains a constant voltage at a microgrid's point of common coupling (PCC) using only local measurements. With the voltage regulation capability, a microgrid can be used to improve power quality so that greatly promote the microgrid's value to power system daily operations. The improved voltage regulation in a power network is demonstrated through simulation tests of a modified IEEE 37-node test feeder. Furthermore, this secondary voltage controller is compatible with existing voltage control devices, such as tap-changing transformers that automatically regulate voltage.

End-use load composition is rapidly changing, particularly towards electronically-coupled or inverter-based load. In particularly, the proliferation of electric vehicles (EV) is expected to continue as consumer prices decrease and charging capability expands. The electric power grid has experienced disruptive technologies since its inception, and it is imperative to study potential future impacts in order to prepare for them if they do occur. This paper highlights fundamental load response of EV chargers, and proposes a set of requirements that are deemed “grid-friendly” to the overall stability and control of the bulk power system at the interconnection-level. Loads exhibiting at least constant current characteristic (constant impedance are very much desirable if possible) with ride-through and reconnection capability will ensure long-term reliability of the grid. The goal is to outline these grid-level requirements in an effort to collaborate with the manufacturing community for sustained grid support from the end-use loads.

This paper presents an assessment of the security-constrained optimal power flow (SCOPF) solutions, under probabilistic generation and transmission contingencies. The proposed SCOPF approach schedules the optimal level of system security by balancing the security cost (i.e. out-of-merit dispatch cost) against the cost of corrective actions and expected cost of energy interruptions due to contingencies. This approach can accommodate any set of N-k generation and transmission contingencies, and the probabilities of the contingencies are sensitive to common mode failures and adverse weather conditions. The results show that common mode failures and adverse weather conditions have a significant impact on the probabilities of the contingencies, and thus on the scheduled levels of security.

Inter-area oscillation in a large power systems draws much attention because it might severely influence system security and reduce transmission capability. The recent large-scale deployment of phasor measurement units (PMUs) enables online measurement-based monitoring and analysis on inter-area oscillatory modes. However, the nonstationary characteristics of measurements become obstacles for oscillation analysis. This work proposes multivariate empirical mode decomposition (MEMD), a multi-channel time frequency analysis method, for ring-down oscillation mode identification. The capability of the MEMD in oscillation mode identification is verified based on a test system. In addition, MEMD is compared with classical Empirical Mode Decomposition (EMD) and Fast Fourier Transform (FFT) for evaluation. The result shows that MEMD can improve oscillation identification through separating different oscillation modes while persevering their phase and amplitude information.

There has been no marginal emission information and/or marginal fuel mix data published by the regional transmission organizations (RTOs) or independent system operators (ISOs) in real-time. This paper presents a support vector machine (SVM) based method to estimate and predict hourly marginal emissions and marginal fuel mix in real-time in the PJM market area. Input to our SVM-based model includes a variety of publicly available data including the real-time locational marginal prices (LMPs), load demand, wind generation, historical marginal fuel data, and other information (such as day of the week and holidays). The results from the SVM are compared with real data from the years 2014 and 2015.

Modernized grid needs ancillary service as a variety of distributed energy resources are connected. Vehicle-to-grid (V2G) application is one of promising distributed energy resources, which enables to transfer bidirectional power between batteries of plug-in electric vehicle and the grid as well as offer ancillary service to the grid. Benefits of V2G application are voltage and frequency regulation, and spinning reserves. To achieve benefits of V2G application, grid-connected inverter (GCI) and its control method are significant. This paper presents control methods of GCI in V2G application to mitigate balanced voltage sag. Voltage sag detector and reactive power compensation are implemented. A 10 kW GCI with output LCL filter and closed-loop control is simulated for V2G application.

Summary form only given. Regulated electricity utilities are required to provide safe and reliable service to their customers at a reasonable cost. To balance the objectives of reliable service and reasonable cost, utilities build and operate their systems to operate under typical historic conditions. When abnormal events such as major storms or disasters occur, it is not uncommon to have extensive interruptions in service to the end-use customers. Society is becoming less tolerant of extensive interruption in services, and it is not cost effective to harden the existing electrical distribution architecture to ensure 100% reliable power; more utilities are examining the deployment of microgrids as a part of the a coordinated resiliency plan. This paper evaluates the feasibility of microgrids as a resiliency resource under three scenarios: as a local resource, a community resource, and as a black start resource. A method of nomograms is proposed, based on dynamic simulations and evaluations of an operational microgrid, to allow operators to quickly evaluate the feasibility of these difference scenarios in operational conditions.

This paper explores the area of double-input single-output DC-DC converters to develop a photovoltaic (PV) source based DC microgrid which is incorporated with maximum power point tracking control technique. The converter used is a fifth-order converter utilizing boost plus single ended primary inductor converter topology which draws power from the two PV sources simultaneously and supplies upstream with reduced ripple current. A control strategy is developed for load voltage regulation by operating the PV in derating mode. The PV sources are controlled to remove any power mismatch, thus maintaining constant voltage at the load end. The voltage is measured at the load end and the error signal is sent to the controller through power line communication (PLC). Results obtained in MATLAB/ Simulink show that the proposed scheme helps in regulating the load voltage by derating the PV sources. This also demonstrates the successful application of the PLC technique in a DC system.

This paper develops an integrated multi-domain simulation tool for distribution systems designed specifically for applications in wind power analysis. The proposed tool consists of steady-state, electromechanical transient, and electromagnetic transient models of voltage sources, transmission lines, transformers, capacitor banks, fixed-speed wind turbines (FSWTs), and wide-slip wind turbines (WSWTs). The test circuit used to demonstrate the multi-domain simulation approach is the IEEE four-node test feeder with a wind turbine connected at the feeder end. The simulation is performed for a one-day period. During this period, wind speed changes every ten minutes, a capacitor is switched on and off, and a temporary single-line-to-ground fault occurs. The results show that the proposed multi-domain simulation tool is able to simulate and analyze long-term power system phenomena.

This paper quantitatively evaluates the uncertainty mitigation by energy storage system (ESS) via complex affine arithmetic-based distribution power flow. First, the affine models of distributed generations (DGs) and ESS under uncertain situations are explicitly established. Then, a forward-backward sweep power flow based on complex affine arithmetic is proposed in distribution systems with DGs and ESS. Third, an index of uncertainty mitigation by ESS to quantify the impacts on the power flow results is defined. Finally, the IEEE 13-bus system case is used to test the proposed evaluation method. The uncertainty mitigation index of ESS is calculated. Test results demonstrate that the presented index can quantitatively reflect the uncertainty mitigation impacts of ESS on separate bus voltage of distribution systems.
