“…M ULTI megawatt grid-scale Energy Storage Systems (ESS), in particular those using batteries as the storage technology (BESS), have typically been used for asset deferral applications, using bulk energy storage to provide peak load shaving, allowing transmission system upgrades to be delayed [1]- [3]. More recent applications for ESSs have included operational services such as primary and secondary reserve provision, and enhanced frequency response (EFR) [4]- [6]. These services require lower overall energy storage capabilities than the reinforcement deferral applications, and so other ESSs that use storage technologies such as ultracapacitors (UC) have been proposed for these applications [7].…”

Grid scale Energy Storage Systems (ESSs) have received significant interest in recent years due to their ability to reduce/defer investment in transmission/distribution networks, as well their ability to act as primary reserve sources and provide emergency support to the transmission system. This paper investigates the dual-purposing of a HVDC-Scale Modular Multilevel Converter (MMC), allowing it to also act as an ESS. This has potential application in primary frequency response provision and other services such as de-coupled power oscillation damping. In the proposed topology a certain percentage of submodules (SM) within the MMC have their capacitor interfaced through a DC-DC converter to an Energy Storage Element (ESE), formed of a battery or ultracapacitor. By applying appropriate control, energy can be exchanged from the ESE to the main SM capacitor of each ESE-SM, and from there to either the AC or DC bus. It was found that for some operating points, an injection of circulating current was required to facilitate exchanging energy with the ESE-SMs. Analysis shows that, for instance, an additional power injection to AC or DC terminal of 0.1 p.u. (10%) is possible with only 4% of the SMs replaced by Full-Bridge ESE-SMs, and no additional SMs added.

“…For the analysis of nonlinear simulations of EPS using Simulink, the following disturbances cases were applied in the system: In the identification of the best bus for the connection of the first BESS in the system, the frequency of Center of Intertia (COI) and average frequency are verified. It is possible to extract the frequency of the COI of the system (f COI ) from (20) [30,31], from the measured frequencies of generators and its inertia constants (synchronous and wind farm):…”

“…BESS devices are not a mature technology, and the mathematical models are still dependent on the specifications of manufacturers. In the literature, different approaches are trying to tackle the BESS modeling, such as those mentioned in [5,6,[9][10][11][12][13][16][17][18][19][20][21][22][23]. As a result, the development of a generic model to represent the dynamic performance of BESS models is a challenge.…”

With the massive penetration of intermittent generation (wind and solar), the reduction of Electrical Power Systems' (EPSs) inertial frequency response represents a new challenge. One alternative to deal with this scenario may be the application of a Battery Energy Storage System (BESS). However, the main constraint for the massive deployment of BESSs is the high acquisition cost of these storage systems which in some situations, can preclude their use in transmission systems. The main goal of this paper is to propose a systematic procedure to include BESSs in power system aiming to improve the power system frequency response using full linear models and geometric measures. In this work, a generic battery model is developed in a two-area test system with assumed high wind penetration and full conventional generators models. The full power system is linearized, and the geometric measures of controllability associated with of the frequency regulation mode are estimated. Then, these results are used to identify the most effective point of connection for a BESS aiming at the improvement of the power system frequency response. Nonlinear time-domain simulations are carried out to evaluate and validate the results.

“…Renewable energy sources are also used to reduce carbon emission and ultimately reduces greenhouse gasses emission from the environment. But, due to the very high penetration of energy systems, there is a need for frequency regulation, hence different control strategies are employed to overcome this problem [24]. The energy storage systems are also needed to compensate for the different characteristics of renewable-based energy systems.…”

Secure and economic operation of the modern power system is facing major challenges these days. Grid-connected Energy Storage System (ESS) can provide various ancillary services to electrical networks for its smooth functioning and helps in the evolution of the smart grid. The main limitation of the wide implementation of ESS in the power system is the high cost, low life, low energy density, etc. However, improved battery technology is changing the scenario rapidly. Also, any mismatch in power demand and supply causes fluctuation in frequency. Therefore, this paper presents a way for reducing the frequency fluctuation using an Advanced Energy Storage System with utility inductors. To compensate for the mismatch of supply and demand, a new system is proposed so that the nominal frequency of the power system is maintained. Due to the very high penetration of energy systems, there is a need for frequency regulation, hence different control strategies are employed to overcome this problem. In case of extreme power supply, the ESS acts as a load and gets itself charged whereas during the power deficit the ESS supplies power to maintain balance in demand and supply, and hence it mitigates the frequency fluctuation. The simulation model contains an ESS connected to a grid with a varying commercial or residential load profile. Simulation results illustrate the effectiveness of grid-connected ESS in minimizing frequency variation.
