Application of energy storage in integrated energy systems — A solution to fluctuation and uncertainty of renewable energy

Urban growth aimed at developing smart cities confronts several obstacles, such as difficulties and costs in constructing stations and meeting consumer demands. These are possible to overcome by integrating Renewable Energy Resources (RESs) with the help of demand side management (DSM) for managing generation and loading profiles to minimize electricity bills while accounting for reduction in carbon emissions and the peak to average ratio (PAR) of the load. This study aims to achieve a multi-objective goal of optimizing energy management in smart cities which is accomplished by optimally allocating RESs combined with demand response (DR) for creating a flexible load profile under RESs and load uncertainty. A comprehensive study is applied to IEEE 69-bus with different scenarios using Sea-Horse Optimization (SHO) for optimal citing and sizing of the RESs while serving the objectives of minimizing total power losses and reducing PAR. SHO performance is evaluated and compared to other techniques such as Genetic Algorithm (GA), Grey Wolf Optimization (GWO) and Whale Optimization (WO) algorithms. The results show that combining elastic load shifting with optimal sizing and allocation using SHO achieves a global optimum solution for the highest power loss reduction while using a significantly smaller sized RESs than the counterpart.

“…For the sake of dealing with the energy shortage and environmental damage issued in the unbridled dependence on mineral fuels, more attention has been focused on alternative renewable energy resources. [1][2][3][4] However, these resources are not good enough to become an alternative to traditional energy due to their intermittent features. Therefore, the development of energy conversion and store appliances is eagerly indispensable to future energy sources.…”

Cobalt‐based sulfide is an excellent electrode material applied to supercapacitors (SCs) because of its good reversibility and abundant nanoforms. However, the feasibility of its practical application is reduced due to lack of stability and some difference with theoretical capacity. Herein, the hierarchical structures of Co3S4 hollow nanotube arrays wrapped with NiCo‐layered double hydroxide nanosheets (Co3S4@NiCo‐LDHs) are successfully fabricated on the nickel foam (NF) as the nonbinder electrode of SCs. Profiting from the synthetic effect of Co3S4 hollow nanotube arrays with effective diffusion channels, and NiCo‐LDH nanosheets with a stable interconnected network, the prepared Co3S4@NiCo‐LDH/NF composite electrode with a unique hierarchical structure attains an amazing areal capacity (7.45 C cm−2 at 2 mA cm−2) and impressive cycle stability (87.7% through 5000 charge and discharge cycles). In addition, the assembled asymmetric supercapacitor (Co3S4@NiCo‐LDH/NF//AC) shows pleasant energy density (0.661 mWh cm−2 under 1.359 mW cm−2). The capacity of the assembled device can still be retained at 92% after 5000 cycles, which verifies the feasibility of the device in practical application.
