Integrating renewable energy sources into the grid can negatively affect its performance without adequate planning. In this study, control variables were optimized to minimize fuel cost, real power losses, emission cost, and voltage deviation. It also met operating constraints, with and without ...
In this equation, KPWM is the amplitude of the PWM sequence, u(t) is the unit step signal, Ts is the period of the PWM sequence and xk (0 ≤ xk ≤ 1) is the duty cycle in the kth period. Following the approach in ref. 16, the spectrum of a uniform-sampling trailing-...
A method of calculation of maximum arc energy was presented to assess the arcing fault damage. Arc model was improved for the calculation of arc energy in low-voltage power systems. The model was expressed as differential equation. Arc voltages in the model were determined with probability method...
The ongoing energy transition requires power grid extensions to connect renewable generators to consumers and to transfer power among distant areas. The process of grid extension requires a large investment of resources and is supposed to make grid operation more robust. Yet, counter-intuitively, incre...
