This paper presents the stability improvement of a multimachine power system connected with a large-scale hybrid wind-photovoltaic (PV) farm using an energy-storage unit based on supercapacitor (SC). The operating characteristics of the hybrid wind-PV farm are simulated by an equivalent aggregated 300-MW wind-turbine generator (WTG) based on permanent-magnet synchronous generator and an equivalent...
This paper presents the stability analyzed results of an integration of a doubly-fed induction generator (DFIG)-based offshore wind farm (OWF) and a permanent-magnet synchronous generator (PMSG)-based OWF fed to a synchronous generator (SG)-based power system through a hybrid high-voltage direct-current (HVDC) link. The hybrid HVDC link consists of a line-commutated converter (LCC)-based inverter...
In this paper we present a hybrid multicast and unicast transmission scheme with superposition coding (SC), i.e., the multicast and unicast signals are overlaid across the entire time and frequency domain. In the SC scheme, the multicast and unicast signals are superimposed and transmitted by BS, in each transmission the superimposed multicast signals are transmitted to a multicast group, while the...
This paper presents the analyzed results of an integrated offshore wind farm (OWF) and seashore wave farm (WAF) connected to an onshore large power grid through a high-voltage direct current (HVDC) link to simultaneously achieve power-fluctuation mitigation and dynamic-stability enhancement. The performance of the studied OWF is simulated by an equivalent aggregated 80-MW doubly-fed induction generator...
Small-signal stability analyzed results of an autonomous hybrid renewable energy power generation/energy storage system connected to isolated loads using time-domain simulations is presented in this paper. The companion paper presents frequency-domain analyzed results of the same hybrid system. The proposed renewable energy power generation subsystems include three wind turbine generators (WTGs),...
