A large amount of wind power has to be curtailed due to the inflexibility of the combined heat and power (CHP) system in the heating season in northern China. The power-to-gas (P2G) technology, which uses electricity to produce hydrogen or synthetic natural gas, has become a promising energy conversion option for the utilization of surplus power energy. In this paper, an integrated natural gas,...

To improve the primary frequency response in future low-inertia hybrid power system a fuzzylogic based frequency controller (FFC) for wind farms augmented with energy storage systems(wind-storage system) and intelligent PV farms for the frequency stabilization is proposed inthis paper. Using system frequency deviations the proposed controller provides bidirectionalreal p...

This paper aims to apply a maximum power point tracking (MPPT) algorithm into a wind turbine with variable speed generator model, jointly the wind energy conversion system (WECS). There are several types of wind turbine in different configurations and their efficiencies in energy extraction are different depending on their aerodynamic designs. In general, their power efficiencies are bounded by...

In off-grid wind energy systems batteries often undergo frequent charge discharge cycles, which reduce battery service life. In addition, due to motor start and other high ‘inrush current’ loads batteries can also undergo high rates of discharge which also degrade battery life. In this paper, a superconducting magnetic energy storage and battery hybrid energy storage system is proposed which is...

Electrical energy concurrent which cannot be stored so must be utilized as soon as it is generated. Therefore it requires an effective balance of power flow within multi area power system. This paper studies about a two area system [Hydro power plant & PMSG based Wind energy conversion system] which is connected through a tie line. Due to the rapid fluctuation in the wind power it causes distur...

This paper conducts a fundamental analysis on the induction generator infinite bus system which is a useful representation for a wind energy converter interfaced to a utility through a transmission line. A third order dynamic model is used to represent the induction generator and the resultant nonlinear system equations are analyzed to derive a condition that guarantees the existence of equilib...

In this paper a procedure for the probabilistic treatment of irradiance and wind meteorological data is reported in order to evaluate the energy potential of a given site as well as the generation of electricity from photovoltaic systems (PVSs) and wind systems (WECSs). In particular the aim of the proposed analysis of recorded meteorological data is twofold: first of all to check if the real p...
