This paper proposes a parallel-resonance bridge type fault current limiter (PRBFCL) to augment the transient stability of a hybrid power system consisting of a photovoltaic (PV) power generation source, a doubly-fed induction generator (DFIG -based winDFIG -basedstem, and a synchronous generator (SG).
Most notably, if Sweden would abandon its present national target for carbon dioxide emissions and instead make full use of the country's participation in international emissions trading, natural gas-fired power would replace onshore wind power as the power generation source with the lowest social cost.
Where "oil-fired generation is the predominant power generation source (e.g. on islands, off-grid and in some countries) a lower-cost renewable solution almost always exists today".
Microgrids with a variety of power generation sources tackle the unreliability issue by combining renewable energy sources with controllable fuel-based generation.
These types of power generation sources generally come in distributed generation system and may operate in standalone and grid connected mode depending on the requirement of the system.
Unlike conventional power generation sources, wind power generators supply intermittent power due to uncertainty in parameters of wind such as its velocity.
The electric power grid is a critical infrastructure that delivers electricity from power generation sources to consumers.
In [25], WT and PV were used as power generation sources to design a hydrogen production and storage system.
To penetrate the electric power market more than the 10-15% range, all renewable power generation sources require storage to match temporal supply with demand.
For power generation, fuel cells offer a number of advantages over conventional thermal power stations such as high efficiency, low pollution and CO2 emissions and the ability to be used as distributed power generation sources at load centres.
Also, since energy is the quantity being sold, this article further presents a simple economic analysis based on EEN and loss savings which can be used to compare alternative power generation sources.
