“…In this sense, the voltage support and harmonic compensation are applied to the BESS so as to improve aspects of energy quality [4,68]; Black Start Capability: Several studies propose the use of BESS to promote the recovery of a total or partial electrical grid subjected to a blackout. Under such conditions, the assistance given by BESS impacts the time of grid interruption and the economic losses [69].…”

Recent works have highlighted the growth of battery energy storage system (BESS) in the electrical system. In the scenario of high penetration level of renewable energy in the distributed generation, BESS plays a key role in the effort to combine a sustainable power supply with a reliable dispatched load. Several power converter topologies can be employed to connect BESS to the grid. There is no defined and standardized solution, especially for medium voltage applications. This work aims to carry out a literature review on the main converter topologies used in BESS and highlight the main advantages and disadvantages of each one. The topologies used for each conversion stage are presented and their combinations are analyzed. In addition, the different services that BESS can carry out when connected to the distribution system are analyzed in order to demonstrate all the main contributions to the electrical systems. Finally, a case study is performed to compare and analyze the converter topologies for BESS, considering some aspects such as efficiency, power quality and number of components.

“…The success of the black start mainly relies on the installation of storage devices, the operation of Microgrid Central Controller (MGCC) and Microsource Controller (MC), along with the mount of microsources with black start capability [27] [28]. The microsources can be classified into two types, Black-Start Distributed Generation (BSDG) and Nonblack-start Distributed Generation (NBDG) based on whether it possesses black start capability [28]. The BSDGs include gas turbines, hydro units, steam units, and DGs with storage devices like batteries and super-capacitors [29].…”

“…batteries and supercapacitors) and is managed by MGCC. In [28], an effective black start strategy for microgrid with PV and hybrid energy storage systems based on a serial restoration approach was illustrated, where the lithium storage system was chosen to perform as the main power supply, and the Vanadium Redox Flow Battery (VRB) system was chosen to perform as BSDG. In [32], the hydro power plant was found that it has the least black start power requirement which its start-up power is only 0.5-1.0% of its generation rating, hence it was chosen to serve as the BSDG installed near the thermal units in a proposed strategy so as to reduce the restoration time.…”

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.

Abstract:The black start capability is vital for microgrids, which can potentially improve the reliability of the power grid. This paper proposes a black start strategy for microgrids based on a parallel restoration strategy. Considering the characteristics of distributed generations (DGs), an evaluation model, which is used to assess the black start capability of DGs, is established by adopting the variation coefficient method. Thus, the DGs with good black start capability, which are selected by a diversity sequence method, are restored first in parallel under the constraints of DGs and network. During the selection process of recovery paths, line weight and node importance degree are proposed under the consideration of the node topological importance and the load importance as well as the backbone network restoration time. Therefore, the whole optimization of the reconstructed network is realized. Finally, the simulation results verify the feasibility and effectiveness of the strategy.
