Economic growth and rising per capita energy consumption, coupled with conducive policy, regulatory framework, fiscal incentive have accelerated development of renewable energy (RE) generation in the country in past few decades. Presently, in renewable generation portfolio, wind constitutes major share and penetration of solar generation is also increasing, However, it is characterized by intermittency & variability. Increasing renewable penetration presents numerous challenges to the system planner as well as grid operator. This paper identifies challenges in grid integration of large scale renewable as well as suggests suitable measures to address them. Need for requirement of other control infrastructure like establishment of Renewable Energy Management Centers (REMC) equipped with advanced forecasting tools as well as Real time measurement/monitoring schemes through WAMS applications, dynamic reactive compensation, energy storage to provide balancing services etc. It also highlights potential of renewable generation in deserts and transmissions plan that serve as a road map up to year 2050. The proposed system presents power-control strategies of a grid-connected hybrid generation system with versatile power transfer. This hybrid system allows maximum utilization of freely available renewable energy sources like wind and photovoltaic energies. For this, an adaptive MPPT algorithm along with standard perturbs and observes method will be used for the system. Also, this configuration allows the two sources to supply the load separately or simultaneously depending on the availability of the energy sources. The turbine rotor speed is the main determinant of mechanical output from wind energy and Solar cell operating voltage in the case of output power from solar energy. Permanent Magnet Synchronous Generator is coupled with wind turbine for attaining wind energy conversion system. Theinverter converts the DC output from non-conventional energy into useful AC power for the connectedload. This hybrid system operates under normal conditions which include normal room temperature inthe case of solar energy and normal wind speed at plain area in the case of wind energy. The simulationresults are presented to illustrate the operating principle, feasibility and reliability of this proposed system.Renewable energy is characterized by intermittency and variability which presents various challenges in its grid integration for maintaining grid stability & security. On the other side, due to large demography, demand varies over the day/week/month as well as on seasonal/regional basis. In order to address above challenges especially in high penetration regime, there is a need to introduce more flexibility with quick ramping features in generation portfolio with mix of various fuel technologies especially Hydro & Gas as well as demand side flexibility. Considering envisaged renewable penetration level by 12th plan and beyond as well as need of identifying challenges.
