Abstract: Constant power loads (CPLs) often cause instability due to its negative impedance characteristics. In this study, the stability of a DC microgrid with CPLs under a distributed control that aims at current sharing and voltage recovery is analyzed. The effect of the negative impedance on the behavior of distributed controller is investigated. The small-signal model is established to predict the system qualitative behavior around equilibrium. The stability conditions of the system with time delay are derived based on the equivalent linearized model. Additionally, eigenvalue analysis based on inertia theorem provides analytical sufficient conditions as a function of the system parameters, and thus it leads to a design guideline to build reliable microgrids. Simulations are performed to confirm the effectiveness and validity of the proposed method.

Energy Management System (EMS) applications of modern power networks like microgrids have to respond to a number of stringent challenges due to current energy revolution. Optimal resource dispatch tasks must be handled with specific regard to the addition of new resource types and the adoption of novel modeling considerations. In addition, due to the comprehensive changes concerning the multi cell grid structure, new policies should be fulfilled via microgrids’ EMS. At the same time achieving a variety of conflicting goals in different microgrids requires a universal and a multi criteria optimization tool. In this work two dispatch-optimizers based on genetic algorithm and mixed integer linear programming for a centralized EMS are introduced which can schedule the unit commitment and economic dispatch of microgrid units. In the proposed methods, different network restrictions like voltages and equipment loadings and unit constraints have been considered.

The advent of microgrids has shifted the focus from centralized power generation to a more distributed manner, involving a mix of different distributed energy resources (DERs). Reciprocating engine driven synchronous generators (referred as gensets) are a common DER used for distributed generation. One of the key concerns with such power networks is the aspect of frequency regulation under large disturbances, especially in an islanded mode of operation, without the support of the utility grid. This works looks at possible solution methods for mitigating large frequency disturbances in an islanded microgrid. Due to steep load changes, the gensets undergo large frequency swings and can be even vulnerable to stalling. The benefits of smart loads are analyzed in this work to prevent such occurrence by temporarily reducing the transient overload on gensets. Another solution to mitigate large frequency deviation is the integration of energy storage system (ESS), but the effectiveness depends on its operation as a grid-forming or a grid-following unit. Important metrics such as frequency nadir during load changes in the islanded microgrid are computed to show the usefulness of ESS in islanded microgrids. For this purpose, analytical methods using reduced-order models are developed and found to provide accurate estimates of frequency deviations under power system disturbances. Generally, ESS units are interfaced with an inverter and when operated in grid-forming mode can offer desired dynamic frequency behavior in an islanded microgrid. Similarly, other inverter-based DERs can also provide good frequency regulation as they share the larger portion of the transient overload compared to gensets. However, under certain scenarios the inverter-based DERs are found to collapse due to this large transient loading and can bring down the whole microgrid system as a result. A better coordination between the different DERs in a mixed source microgrid is facilitated in this work to guarantee adequate inertial response. Such a scheme redistributes the unequal transient load sharing between gensets and inverter-based DERs and provides improved frequency regulation, without compromising on the survivability of islanded microgrids. The use of smart loads is also incorporated as an additional feature in the overall coordinated scheme for withstanding extreme scenarios.

This book comprises ten articles covering different aspects of power quality issues in microgrids and distributed generation (DG) systems, including 1) Detection and estimation of power quality; 2) Modeling; 3) Harmonic control for DG systems and microgrids; 4) Stability improvements for microgrids. Different power quality phenomena and solution were studied in the included papers, such as harmonics, resonance, frequency deviation, voltage sag, and fluctuation. From a network point of view, some papers studied the harmonic and stability issues in standalone microgrids which are more likely to cause power quality problems. Other papers discussed the power quality problems in microgrids which are weakly interconnected with the main distribution grid. In view of the published papers, there is a trend that increasingly advanced modeling, analysis, and control schemes were applied in the studies. Moreover, the latest works focus not only on single-unit problems but also multiple units or network issues. Although some of the hot topics are not included, this book covers multiple aspects of the current power quality research frontier, and represents a particularly useful reference book for frontier researchers in this field.

Many innovative control techniques have been used for enhancing the stability of microgrid as for proper load sharing. The most common method is the use of droop characteristics for decentralized load sharing. The power sharing of distributed sources is the main focus of this dissertation. In this book, an angle droop controller is used to share power amongst converter interfaced DGs in a microgrid. An enhanced frequency droop controller is also proposed for better dynamic response and smooth transition between grid connected and islanded modes of operation. Power quality enhanced operation of a microgrid in presence of unbalanced and non linear loads is also addressed in which the DGs act as compensators. A frequency and voltage isolation technique between microgrid and utility is shown by using a back-to- back converter. For accurate load sharing, the droop gains have to be high, which has the potential of making the system unstable. To improve this situation, a supplementary droop controller is designed. Two methods are proposed for load sharing in an autonomous microgrid in rural network with high R/X ratio lines.

Microgrids with natural gas engine driven distributed energy resources (DERs) are more likely to be favored by both industries and utilities in the near future because of their low costs, which, in turn, is due to the newly found shale deposits at many places in the world. Such DERs can be connected either directly or through an inverter to the utility/load. Therefore, they are referred to as synchronous generator-based DERs and inverter - based DERs respectively. In this research work, the synchronous generator-based DER and inverter-based DER installed at the CERTS Microgrid test bed have been modeled. The dynamic and steady-state performance of the models were evaluated by verifying the model results against experimental tests conducted at the CERTS microgrid. A key contribution of this modeling effort is that the developed models of the DERs are simple and can fairly represent to a reasonable degree of accuracy the dynamic behavior without infringing on the confidential information of the commercial equipment manufacturers. Such models can easily be multiplied wherever necessary with appropriate scaling to facilitate analysis of numerous scenarios and case studies that may be otherwise impractical due to resource limitations at the field site to undertake actual testing ¿ or at the very least expensive and time consuming.
