“…For three-phase unbalanced systems, the Y is computed considering each phase as a node (each phase node) and the unbalanced branch and shunt admittances. Let Y = G + jB, V = V re + jV im , and I = I re + jI im , then (23) can be separated into real and imaginary parts:…”

“…None of these formulations incorporated the use of droop control for islanded microgrids formation. Most of the works that considered the droop control of microgrid emergency operation (including the black start) did not formulate the black start operation of the studied microgrid systematically but rather were mostly rule-based and for concept verification through transient simulation and experimental studies [20][21][22][23]. However, as the size of the microgrid and the operation considerations increase, a rule-based approach becomes less reliable in finding a feasible and optimal (or near-optimal) solution.…”

The electricity grid faces the possibility of outages due to extreme weather events, cyber-attack, and unexpected events. When these unwanted events occur, it is desired that electricity be restored as soon as possible to meet the power demands of critical loads. The microgrid approach to power restoration holds a lot of promise, since microgrids can operate in island mode. This paper presents a novel sequential restoration methodology for microgrid black start. The microgrid architecture considered is assumed to be operating in multi-master mode. The master distributed generators (DGs) are coordinated to operate together through droop control. Several operational constraints are formulated and linearized to realize a mixed-integer linear programming (MILP) problem. The method is studied on an islanded microgrid based on a modified IEEE 13 node test feeder. Detailed transient simulation in PSCAD was used to verify the accuracy of the restoration methodology. The developed restoration method can maximize the energy restored while ensuring good voltage and frequency regulation, and ensure that power scheduling mismatch is shared in the desired proportion.

“…In [29], an optimized black start scheme using a DG with storage devices and V/f control was verified as feasible among different schemes by assessing LV distribution network building time and minimum load power factor. In [30], two methods were proposed to investigate the grid restoration: constantly updated power setpoints and fixed droop. However, each of them has both advantages and disadvantages.…”

The concept of generating electricity from renewable sources has been developed to solve the problems raised by environmental pollution and diminishing fossil fuel resources. Integration of clean renewable generation into existing electrical systems has been proven to benefit both power system operators and customers. However, a number of technical and economic challenges still exist with regards to effective integration and optimal utilization of such sources. One of the issues much debated recently is the provision for islanded operation in distribution networks utilizing the locally available generation. There are many obstacles and challenges concerning technical, economic and regulatory aspects of islanded operation which attract a significant amount of research worldwide. This review paper covers the stateof-the-art in research on islanded systems, specifically concerning: generation control, islanding detection, protection, and other functions such as power-sharing and black start capability.

“…During the blackout the [11], as described in [8]. Once the microgrid has achieved a steady-state operation, the DERs controlled with active and reactive power set-points, the grid-feeding inverters [12], can be connected [13]. This helps reducing the amount of power provided by the batteries and therefore the discharging time, given that the amount of power provided by the storage systems to support the voltage and feed the loads is consequently reduced.…”

The increase of installed renewable resources and energy storage systems could deeply change the black-start procedure, from the classical top-down to a microgrid-based approach. In this sense, an Emergency Energy Management System (EEMS) is developed to the isolated grid that results after the blackout to optimize the restoration process. The proposed EEMS coordinates the elements of the microgrid in order to provide the required electrical power to critical loads, managing the State of Charge (SOC) of the batteries and the available power from the remaining resources. The proposed approach is tested with a Real Time Digital Simulator (RTDS).
