Abstract |
Today, there is an ever-increasing tendency towards the use of renewable energy resources due to the depletion of fossil fuels ones. This study presents an approach based on the probability density functions (PDF) of wind speed and solar irradiance level by which different scenarios for the output power of the resources are extracted. Then, the production schedule of power system in the electricity market is developed based on the extracted generated powers. In the next step, the scenario of the use of battery as an energy storage system (ESS) is put forward in order to compensate the uncertainty of the output power of renewables. Consequently, the optimal capacity of the battery is obtained interactively with the market in the form of an optimization problem using differential evolution algorithm (DE). In addition, the use of battery as a no-spinning reserve of system with the aim of reducing the spinning reserve (SR) level of system is evaluated. The proposed method will be tested on a distribution feeder in Wellington, New Zealand and the obtained results will be analyzed. |
