Power systems are experiencing massive changes in their generation patterns with increasing penetration of decentralised renewable generation and decommissioning of thermal plants. Such changes in generation patterns will bring significant challenges to the black start arrangement. Conventional black start process relies on large thermal plants connected at the transmission level to energise the system using a "top-down" approach. This may no longer be adequate or applicable in future networks due to the closure of most thermal plants. This paper will investigate the feasibility of using Distributed Energy Resources (DERs) to provide a "bottom-up" black start approach. Compared with the conventional approach, using DERs for black start has potential advantages of reduced restoration time and more flexible recovery procedure. In this paper, a comprehensive review of the existing black start studies utilising DERs will be provided. Additionally, several case studies using a distribution network model containing multiple resources such as wind, micro-hydro generator, and energy storage will be presented to demonstrate the feasibility of providing black start capability by DERs. Furthermore, the associated technical issues that need to be considered to enable such a black start approach will also be discussed, along with feasible solutions and suggestions for further investigation.

“…Reference [9] presented the black-start experiment using pumped-storage units as the power supply in the Shandong power grid, China. Reference [10] analyzed the black-start experiment using hydropower turbine and gas turbine as the power supply in India. However, the uneven distribution of water resources and the lack of water resources in some areas limit the construction of hydropower units; gas turbines require high-power diesel generator sets to provide start-up power and need to be turned on regularly for maintenance.…”

With the rapid growth of installed capacity of photovoltaic (PV), the PV power stations equipped with energy storage (ES) have become a new type of black-start power supply. Taking the Photovoltaic-Battery Energy Storage Systems (PV-BESS) as the black-start power source can improve the black-start ability of the regional power grid and broaden the application prospect of PV power generation. In this paper, a stratified optimization strategy for black-start of PV-BESS is proposed, which combines the key issues in the process of black-start of PV-BESS. Stratified optimization strategy is divided into data analysis layer, optimization coordination layer and scheduling control layer. The data analysis layer combines the requirements of the black-start process. Firstly, the similarity matrix ranking method is used to improve the PV power prediction method. Secondly, based on probability inclination, the PV power index is designed to evaluate the feasibility of black-start by calculating the PV lower limit power and the executable probability inclination. The optimization coordination layer is based on the state space model of blackstart of PV-BESS, combined with the control strategy of PV as the main part and ES as the auxiliary part, the optimization objectives of the maximum utilization rate of PV and tracking the ideal value of state of charge (SOC) of ES is formulated. The optimal model is solved by model predictive control, and the output power of PV and ES is controlled to complete the black-start process. The actual historical data in the power grid with a high proportion of PV sources are used as the basic data for simulation. The simulation of black-start based on MATLAB/Simulink verifies the rationality of the stratified optimization strategy, which provides a reference for the realization of black-start of PV-BESS.

“…In emergency circumstances such as utility blackouts, the microgrid can change to islanded mode, which cuts off the upstream utility grid [77], [78]. Once the blackout occurs, effective methods such as black start need to be used to restore the grid back to its normal operation state to reduce the impact on consumers and the economic loss [79]. In general, a black start is restoring the microgrid operation without relying on the external utility power grid.…”

Three-phase alternating current (AC) has dominated the global power systems for over a century due to advantages such as readily transforming voltages with different levels, high-efficiency generation, transmitting power over long distances, etc. However, direct current (DC) power systems have recently gained popularity because they enable the more efficient and dependable integration of renewable energy sources such as solar, wind, fuel cells, and battery energy storage systems (ESSs). Thus, interlinking AC and DC subgrid power systems to be hybrid AC/DC microgrids presents a promising solution to energy and environmental issues.Due to the intermittence characteristic of renewable energy resources, energy storage (ES) is important to help mitigate the power imbalance between generation and consumption in AC/DC microgrids and to maintain the AC grid frequency and DC bus voltage. The improvement in power conversion efficiency and the reduction of carbon emissions into the environment are the major benefits of AC/DC hybrid microgrids. To achieve comprehensive coordination for hybrid microgrids, the most common implementation for the entire system is a centralized energy management system (EMS) with a communication link between the central controller and other system components. The primary drawbacks of centralized control are relatively low system reliability due to the need for a communications network and relatively slow response time due to the communication delay. Therefore, proper coordination controls of AC/DC microgrids need to be implemented to ensure stable, reliable, and efficient system operation and supply the load with high power quality. The modeling for different typologies, such as bipolar DC networks and nine-switch-based configurations of hybrid microgrids, investigates i Abstract the effectiveness of the associated decentralized and coordination control power management schemes. The objective is to minimize the power system frequency deviation of the AC subgrid and the voltage deviation of the DC subgrid caused by load changes and renewable power fluctuations. Advanced coordination control, VRM Voltage Regulation Mode VSC Voltage Source Converter VSM Virtual Synchronous Machine xii voltage regulation was complex, inefficient, and costly compared to AC voltage regulation using transformers. Therefore, AC appeared to be the better option,and it has become the norm for energy transmission and distribution ever since.According to [12], the implementation of DC systems can be traced back more than a decade ago. However, its popularity did not increase much until the last decade, when renewable energy developed dramatically. The expansion of popular renewables such as PV and energy storage (ES) including super-capacitors and batteries, which are all compatible with DC, has accelerated the popularity of DC power networks [13], [14]. Almost all electrical appliances are connected to an AC power supply in the existing power network. Specialized AC/DC rectifiers must convert utility AC power to DC power. H...
