The main objective of this article is to propose a special protection system (SPS) execute efficient remedial actions prevent mid-term and long-term voltage instabilities. In method, when the operating point (OP) leaves normal operation state, proposed SPS initiated required corrective bring OP back state maintain bus voltages above prespecified thresholds. Considering local nature Volt/Var con...

The power system continuously deals with frequency fluctuations. When a disturbance occurs, the transmission operators rely on underfrequency load shedding (UFLS) scheme to address severe (UF) events maintain at permissible level and prevent blackouts. Defining settings of conventional UFLS is very complex problem due nonlinear nature response, size vast because number UF-relays spread system. ...

A constant worldwide growing load stress over a power system compelled the practice of reactive injection to ensure an efficient network. For this purpose, multiple technologies exist in knowledge market out which paper emphasizes usage flexible alternating current transmission (FACTS) and presents comparative study static var compensator (SVC) with synchronous (STATCOM), inducted real electric...

Much attention has been paid to optimizing smart grids (SGs) and microgrids (MGs) protection schemes. The SGs’ operation in different operating modes (especially grid-connected islanded conditions) various system configurations (such as the outage of each distribution generations) adversely influence system. adaptive schemes using setting groups are suitable reliable solutions achieve a fast pr...

The results of low-frequency oscillations identification in the Republic Kazakhstan power grid by using a Wide Area Measurement System are presented and an algorithm for damping is proposed this paper. Analysis weakly damped inter-area revealed constant mode with frequency range 0.3‒0.4 Hz. It was determined that at these oscillations, amplitude active fluctuations along transmission line 150 M...

The optimized design of a freestanding hybrid microgrid for various distinct dispatch controls is assessed in this paper, which considers the optimal sizes individual components, system response, and reliability analysis. effective management stand-alone islanded smartgrids are getting increasingly importance influences as prevalence renewable energy microgrids grows. Melville Island, off coast...

In this study, a new methodology is proposed to perform optimal selection of conductors in three-phase distribution networks through discrete version the metaheuristic method vortex search. To represent problem, single-objective mathematical model with mixed-integer nonlinear programming (MINLP) structure used. As an objective function, minimization investment costs together technical losses ne...

Hydropower has been the primary source of electricity in Bhutan, and to achieve power security sustainability, alternative renewable energy sources (RES) such as solar wind are being explored. However, literature reviews present that bus voltage is most affected parameter during integration. Therefore, this paper presents impact on due integration RES into network Bhutan. The measured weather g...

As an alternative to traditional fossil fuel extracted energy, wind energy has been acknowledged as one of the most important sources of renewable energies in the world. This clean and natural source of energy could be a key to solving the worldwide energy crisis with low environmental impact. The increased penetration of wind power into the power grids mean the impact of the wind turbines on t...
