“…Among various electrical energy storage technologies, battery and supercapacitor are two types which offer high energy and power density features respectively [29]. As T-MMC SMs can perform flexible control and management in terms of voltage balancing, state-of-charge (SoC), health, etc., the distributed deployment of rechargeable batteries and/or supercapacitors (SCs) is applicable [41], [42]. Although, from the system inertia point of view, it is desirable to equip the converter with as much ESEs as possible, integrating ESEs into the Stage-I is not necessary for the fulfillment of additional functions.…”

This paper proposes a novel modular multilevel converter (MMC) named 'T-type MMC' (T-MMC) for reliable, controllable and efficient performance in energy conversion applications. Circuitry configurations and control structures are presented, with respect to fundamental and additional functions. The T-MMC topology consists of two solid-state power stages (Stage-I and Stage-II), which are coordinated for ac and dc fault tolerance, increased ac-side voltage synthesis, etc. Energy storage elements can be integrated into the submodules. As a result, the T-MMC based energy storage system can not only increase system inertia but maintain continuous power transmission during faults. A thyristor forcedcommutation technique facilitates actively-controlled utilization of symmetrical thyristors in the conduction path; thus T-MMC normal-mode operation losses can be equivalent to those of the conventional half-bridge MMC. Simulation and experimentation demonstrate the performance of the T-MMC. Index Terms − T-Type Modular Multilevel Converter, ac/dc fault, thyristor, energy storage system.

“…This topology has the same advantages inherent to multilevel converters, as already mentioned for the CHB converter. Besides, it is observed active power support between dc and ac system and a greater freedom of SOC control, since the converter has 3 circulating currents [45][46][47][48]. This topology presents flexible disposition of the batteries between the cells of each phase, according to Fig.…”

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 optimal capacity of the battery and ultracapacitors can be obtained through the above method, but the local temperature characteristics still need to be considered in the actual selection of the battery and ultracapacitors. The output capacity of the battery can be adjusted according to the local actual temperature conditions [17]:…”

The capacity of an energy storage device configuration not only affects the economic operation of a microgrid, but also affects the power supply's reliability. An isolated microgrid is considered with typical loads, renewable energy resources, and a hybrid energy storage system (HESS) composed of batteries and ultracapacitors in this paper. A quantum-behaved particle swarm optimization (QPSO) algorithm that optimizes the HESS capacity is used. Based on the respective power compensation capabilities of ultracapacitors and batteries, a rational energy scheduling strategy is proposed using the principle of a low-pass filter and can help to avoid frequent batteries charging and discharging. Considering the rated power of each energy storage type, the respective compensation power is corrected. By determining whether the charging state reaches the limit, the value is corrected again. Additionally, a mathematical model that minimizes the daily cost of the HESS is derived. This paper takes an isolated micrgrid in north China as an example to verify the effectiveness of this method. The comparison between QPSO and a traditional particle swarm algorithm shows that QPSO can find the optimal solution faster and the HESS has lower daily cost. Simulation results for an isolated microgrid verified the effectiveness of the HESS optimal capacity configuration method.
