Hybrid Models of Alternative Current Filter for Hvdc

Abstract

Abstract. Based on a hybrid simulation concept of HVDC, the developed hybrid AC filter models, providing the sufficiently full and adequate modeling of all single continuous spectrum of quasi-steady-state and transient processes in the filter, are presented. The obtained results suggest that usage of the hybrid simulation approach is carried out a methodically accurate with guaranteed instrumental error solution of differential equation systems of mathematical models of HVDC.

Study of photovoltaic systems using modelling and simulation

“…Electrical energy produced by a photovoltaic panel has a variable character in time due to several factors, among which we mention: alternation day/ night, alternation of clear sky/ overcast sky, etc. The systems through which energy flow is conditioned in photovoltaic systems are called static converters [8,9]. In addition to function of conditioning flow of electricity, static converters in composition of photovoltaic systems also fulfil role of monitoring and control to process of charging/ discharging rechargeable batteries.…”
