Impacts of photovoltaic/wind turbine/microgrid turbine and energy storage system for bidding model in power system

摘要

In this work, a new model has been developed to examine and present a bidding method and a suitable strategy for large consumers. The proposed model is consists of different energy suppliers as: wind micro turbines, energy storage systems, renewable energy sources (wind turbine and solar system) and bilateral contracts. To solve the mentioned problem, a hybrid robust-stochastic method in which the load uncertainty, temperature and wind speed, the amount of solar radiation and the cost of purchasing energy are considered in the proposed model. In this work, load uncertainty and other uncertainties are modeled. Also, two types of weibull and normal distribution are utilized, that the first distribution is used to create wind speed scenarios and second distribution to create solar radiation, temperature and electricity market prices scenarios. Bidding and offering curves have been obtained via a mixed-integer linear programming model and this model has a significant effect on uncertainty in the demand of the large consumers. Effectiveness of proposed method is applied on standard system through different scenarios. Obtained results shows the efficiency of proposed method in large consumers and the presence of load uncertainty. (C) 2019 Published by Elsevier Ltd.
