Researchers from IIT, Guwahati, have developed optimized control schemes for active power distribution networks that enable coordinated operation of photovoltaic (PV) power generation and charging stations for electric vehicles. The sustainability of electric vehicles (EV) can be increased if the capacity to charge these vehicles is also based on renewable energy sources such as solar energy.
However, intermittent solar power leads to problems with voltage fluctuations in the power distribution networks. In addition, the charging of electric vehicles is currently uncoordinated, leading to undervoltage of the distribution networks and associated efficiency losses.
A coordinated control approach for the power distribution system is required to reap maximum benefits from renewable energy generation and EV power supply.
The release said the research team has developed a three-stage model predictive control (MPC) approach to plan the charging of EVs and other devices.
The three phases include coordination of the volt-var devices in two different timescales, receipt of the reactive power setpoints by the local controller, and EV charging scheduling in accordance with the balance between operating costs and customer satisfaction.
