Abstract: The demand of electricity is increasing day by day and conventional sources of electricity is very limited. Renewable energy is becoming very attractive source of electricity to meet the load and protect the environment. Power system of India is transforming towards integration of high renewable energy. The challenges in integration of renewable energy are its uncertain availability and old existing power network infrastructure. As demand is also uncertain, so renewable energy cannot meet the demand without any ancillary system. Integrating some energy storage system with renewable energy system can solve uncertainty problem of renewable energy. To integrate more renewable energy upgradation of power system and lines are required. Most of the time transmission lines are heavily under loaded from its actual power handling capacity, as worst possible power handling capacity of line is considered while scheduling power to generators. Actual power handling capacity of line depends on many environmental factors. In this work, The effect of integrating high renewable energy and increasing storage type units on fuel cost of conventional power generation and curtailment of renewable energy have been studied with a IEEE 14 bus system. For an old 75-bus transmission system of Uttar Pradesh (India) with integration of all recent proposed solar power plant in Uttar Pradesh, the scheduling has been done considering static and weather based dynamic line rating. As the actual loads have different voltage based real and reactive power demand, a voltage dependent dynamic (ZIP) load model has been considered here for load modeling. Scheduling with a penalty on overloading of line and penalty on voltage deviation from nominal voltage has been done with dynamic and static line rating to see the difference of minimum possible overloading of line with static line rating and dynamic line rating. With this scheduling strategy, high renewable energy can be integrated to an existing system with minimum upgradation of lines.
