“…However, conventional power suppliers or generators have initial time to generate electricity, but the system needs a quick response against the demand. Several studies 17,32,33,42 show that storage systems provide solutions for voltage support and grid regulation. For instance, battery storage systems are operated by battery management systems.…”

Summary As the world's population and living standards rise, energy suppliers will face increased electrical energy needs. Furthermore, the European Commission has established a goal to reduce fossil fuel use and greenhouse gas emissions in accordance with the Kyoto and Paris Protocols. As a result, governments are more likely to integrate renewable energy into their electricity grids. However, since renewable energy resources are intermittent, power grid systems confront considerable hurdles. By overcoming the intermittency of renewable energy resources, battery storage systems are one way to optimize load and demand. Many studies show that the stored energy can be used in high demand. This may reduce the cost of production in the long run. Energy storage systems can also provide voltage and frequency regulation to power systems when connected to the transmission and/or distribution lines. The application and benefits of battery storage devices in electricity grids are discussed in this study. The pros and disadvantages of various electrochemical batteries, including their structure, energy capacity, and application areas, are compared and summarized and their benefits and drawbacks are included. Finally, the research demonstrates how electrochemical battery technologies and power grids have collaborated.

“…It requires a long time to overcome the performance disturbance and reach convergence. In [23], Zafar et al proposed a multi-timescale voltage stability constraint V/VAR optimization method, utilizing the multi-timescale optimization method to improve the steady state stability and security of the smart distribution grid. In [24], Li et al proposed a cloud-edge-device collaborative high-concurrency access management algorithm based on multi-timescale joint optimization of channel pre-allocation and load balancing degree to meet the requirements of high concurrent access for massive IoT devices.…”

The rapid advancement of cloud-edge-end collaboration offers a feasible solution to realize low-delay and low-energy-consumption data processing for internet of things (IoT)-based smart distribution grid. The major concern of cloud-edge-end collaboration lies on resource management. However, the joint optimization of heterogeneous resources involves multiple timescales, and the optimization decisions of different timescales are intertwined. In addition, burst electromagnetic interference will affect the channel environment of the distribution grid, leading to inaccuracies in optimization decisions, which can result in negative influences such as slow convergence and strong fluctuations. Hence, we propose a cloud-edge-end collaborative multi-timescale multi-service resource management algorithm. Large-timescale device scheduling is optimized by sliding window pricing matching, which enables accurate matching estimation and effective conflict elimination. Small-timescale compression level selection and power control are jointly optimized by disturbance-robust upper confidence bound (UCB), which perceives the presence of electromagnetic interference and adjusts exploration tendency for convergence improvement. Simulation outcomes illustrate the excellent performance of the proposed algorithm.

“…In [8], voltage stability is considered in a wind power planning problem. To enhance the steady-state stability of smart distribution system, [9] suggests a multitimescale voltage stability constrained volt/var optimization model.

This paper proposes a voltage stability constrained optimal power flow (VSC-OPF) for an unbalanced distribution system with distributed generators (DGs) based on semidefinite programming (SDP). The AC optimal power flow (ACOPF) for unbalanced distribution systems is formulated as a chordal relaxation-based SDP model. The minimal singular value (MSV) of the power flow Jacobian matrix is adopted to indicate the voltage stability margin. The Jacobian matrix can be explicitly expressed by ACOPF state variables. The nonlinear constraint on the Jacobian MSV is then replaced with its maximal convex subset using linear matrix inequality (LMI), which can be incorporated in the SDP-based ACOPF formulation. A penalty technique is leveraged to improve the exactness of the SDP relaxation. Case studies performed on several IEEE test systems validate the effectiveness of the proposed method.
