This paper deals with the solution of the issue of exceeding the permissible levels for long-term flicker effect Plt in industrial distribution systems. Flicker effect in distribution systems is often exceeded as a result of the connection of electric arc furnaces, which exhibits high variable electrical power in-take. The article shows the benefits of measures on the steel plants, the distribu...

According to the conclusions of the study “Smart Portugal 2020”, the Information and Communication Technologies (ICT) can contribute to a reduction of 15% in our ecological footprint. The role of innovation and the early adoption of solutions that could reduce consumption in all economical sectors will be vital to the 20/20/20 European Strategy [1]. Active network management for generation, sto...

One ultimate goal of power network planning is to construct power systems that are environmentally friendly. However, it is still a challenging issue to efficiently consider environmental factors in power network planning problems due to the complexity and the diversity of environment. This paper presents a nonlinear approach to formulate the multi-dimensional spatial power network planning pro...

Electric power, water, natural gas and other utilities are served to consumers via functional sources such as electric power substations, pumps and pipes. Understanding the impact of service outages is vital to decision making in response and recovery efforts. Often, data pertaining to the source-sink relationships between the service points and consumers is sensitive or proprietary, and is, th...

regarding the nature of non-linear discrete placement, and in order to determine the optimal capacity of the substation, the goal in the present study will be a number of local optimum points. in this research, the problem of optimal placement posts to reduce power losses by considering distributed generation (dg). in formulating the objective function, geographical distribution density in the ...

This paper proposes the solutions to prevent over-voltage for the 220 kV distribution substations with several different voltage levels. The motivation comes from the failures of surge arrester number 2 of phase B at the transformer number 2 (CS2BAT2) of the Vietnamese 220 kV Thainguyen substation due to the over-voltage. The main objective is to enhance the operating stability of a scattered c...
