Based on the Bouc-Wen model, a nonlinear hysteretic restoring force model is established with dynamic equations. The hardening and softening of material after reaching yield limit are described by force-displacement curve. Gamultiobj algorithm group search optimization (GSO) used to fit identify hysteresis curves, respectively. effectiveness for identifying parameters verified, effects two algo...

The objective of this work is to predict the temperature of the different types of walls which are Ferro cement wall, reinforced cement concrete (RCC) wall and two types of cavity walls (combined RCC with Ferrocement and combined two Ferro cement walls) with the help of mathematical modeling. The property of low thermal transmission of small air gap between the constituents of combine materials...

Incorporating photovoltaic (PV) inverters in power distribution systems via static synchronous compensators (PV-STATCOM) during the nighttime has lately been described as a solution to improve network performance. Hunter prey optimization (HPO) is introduced this study for efficient PV-STATCOM device allocation systems. HPO generates numerous scenarios how animals could act when hunting, some o...

This paper based on the metaphor of specialization and cooperation in steppe tribes of the human society, tribe glowworm swarm optimization (TGSO) algorithm was presented to solve the problem of low precision and easy to fall into local optimization of the glowworm swarm optimization (GSO) algorithm. In the proposed tribe glowworm swarm optimization approach, all glowworms are divided into a ce...

Recently, economic and environmental problems have created a strong attitude toward utilizing renewable energy sources (RESs). Nevertheless, uncertainty of wind and solar power leads to a more complicated energy management (EM) of RESs in microgrids. This paper models and solves the EM problem of microgrid from the generation point of view. To do this, mathematical formulation of a grid- connec...

Attaining highly secure and safe operation of the grid with acceptable voltage levels has become a difficult issue for electricity companies that must adopt remedial actions. The usage PV solar farm inverter as static synchronous compensator (or PVSTATCOM device) throughout night recently been proposed way to enhance system performance. In this article, novel artificial rabbits’ optimization al...

Constraint satisfaction problem (CSP) has been actively used for modeling and solving a wide range of complex real-world problems. However, it proven that developing efficient methods CSP, especially large problems, is very difficult challenging. Existing complete problem-solving are in most cases unsuitable. Therefore, proposing hybrid CSP-based increasing interest the last decades. This paper...

In recent years, unmanned aerial vehicles (UAVs) have become the trend for different types of research and applications. UAVs can accomplish some technical risky tasks while still being safe, mobile, inexpensive to operate. However, need flying ad-hoc networks (FANET) operate in inaccessible or infrastructure-less areas. Subsequently, many military civil applications, are connected ad hoc. FANE...

The demand for high-speed automatic train operation (ATO) system brings new opportunities and challenges the railway field. requirements of energy consumption, punctuality, safety smoothness are also increasing, especially research on saving trains ushers in a broader development space. This paper proposes quantitative functions four energy-saving performance indexes multi-objective optimizatio...

Multi-area power systems (MAPSs) are highly complex non-linear facing a fundamental issue in real-world engineering problems called frequency stability (FSP). This paper develops an enhanced slime mold optimization algorithm (ESMOA) to optimize the tuning parameters for cascaded proportional derivative-proportional integral (PD-PI) controller. The novel ESMOA proposal includes new system that c...
