Different approaches to limiting the levels of electromagnetic pollution in the electrical networks are discussed. Overview of the main principles used as basis for IEC EMC standards, CIS Standard 13109-97 and IEEE Standard 519-1992 is presented. Time-varying nature of the electromagnetic processes behavior in power systems is highlighted and expressions for power quality indices based on spectral...
Smart grid is increasingly seen as a means to facilitate climate friendly renewable energy sources (renewables) and to enable efficient use of electricity. For example, modern electrical networks can link wind- and solar power with electric cars. A consequence of smart grid is a drastic increase in use of electronics in the power system. This makes the satisfactory function of electrical and electronic...
The paper presents a neural method of estimation of instantaneous voltage at a considered node of electric power system feeding nonlinear loads. There are presented simulations conducted using MATLAB/SIMULINK as well as results of measurements obtained for a real power network. Application of artificial neural networks enables comprehensive investigation of voltage at a PCC (Point of Common Coupling)...
