Power Quality Improvement in Solar-Wind based Power System using BESS

As solar photovoltaic and wind based power generation becomes more commonplace, the inherent intermittency of the solar and wind resource poses one of the great challenges to those who would design and implement the next generation smart grid. Speci?cally, grid-tied solar power generation is a distributed resource whose output can change extremely rapidly, resulting in many issues for the distribution system operator with a large quantity of installed photovoltaic devices. Battery energy storage systems are increasingly being used to help integrate solar and wind power into the grid. These systems are capable of absorbing and delivering both real and reactive power with sub-second response times. With these capabilities, battery energy storage systems can mitigate such issues with solar-wind power generation as ramp rate, frequency, and voltage issues. Beyond these applications focusing on system stability, energy storage control systems can also be integrated with energy markets to make the solar and wind resource more economical. Providing a high-level introduction to this application area, this paper presents an overview of the challenges of integrating solar and wind power to the electricity distribution system.In this paper a solar-wind based power system model is made. To smoothen the intermittency of the solar and wind resources a battery energy storage system (BESS) is employed. The battery energy storage system stores the energy when excess power is available and releases the stored energy when demand is higher than the supply. A PI controller based control scheme is implemented for this purpose and an MPPT is used for wind turbine to extract the maximum power from the wind resource.The validity of the control scheme is checked through the MATLAB simulation of the solar-wind based power system.
