| Abstract | Wind power generation is in the developing phase in most of the countries and the capacity additions are increasing day by day. The i mportance of wind penetration is that it can reduce or replace the existing conventional gen eration, thereby providing lots of benefits to the end-users. To increase the wind pen etration, the wind farms have to be connected to the best suitable bus and should be in tegrated with an intelligent robust controller. Voltage and angle instability are the m ain limiting factors for maximizing the wind penetration and grid control authorities are l imiting the maximum wind penetration limit for maintaining grid stability. Lots of wind energy investment is hence, left underutilized. This research work is an attempt for identifying the maximum safe instantaneous wind penetration model by the optimiz ation of Grid Control Parameters. A new approach based on Particle Swarm Optimization ( PSO) algorithm has been developed and suggested to identify the maximum per missible safe instantaneous wind energy penetration limit. Optimal Wind farm placeme nt methodology for maximizing the wind penetration has been suggested by taking into account voltage sensitivity index. The concept of robust intelligent PSO based wind penetr ation controller has been introduced to facilitate healthy maximum penetration by the op timization of grid control parameters. Three control algorithms, namely load increase, gen eration displacement and combined generation displacement and load increase have been embedded in the controller for suiting into various types of power grids. The meth odologies and techniques for enhancing the maximum wind penetration by using the Flexible AC Transmission Systems (FACTS) controllers have also been included in the controller. Static and dynamic models by considering turbine governor, aut omatic voltage regulator etc have also been incorporated in the study and the small s ignal stability at higher penetration levels are analyzed by conducting the eigenvalue an alysis of the complete power grid. The architecture of the maximum wind penetration contro ller has also been suggested. All the above mentioned methodologies and approaches are te sted with IEEE 14-bus standard system and Kerala grid 25-bus practical system. The results have shown that the maximum instantaneous wind energy penetration limit in percentage and also maximum safe bus loading and generation displacement point explicitly beyond which system drives into instability. |
