Assessing the Impact of Demand Response on Microgrids with the Aim of Increasing Reliability Considering Distributed Generation Resources

Today, the utilization of renewable resources has been increasing widely. In microgrids, to supply the energy needed by consumers, renewable energy sources such as wind turbines, photovoltaic systems and fuel cells are used in addition to production sources and energy storage devices. Along with the advantages of using renewable energies, the uncertainty in their amount and also the dependence of their production on natural resources have made their growing process difficult. One of the important and inherent features of renewable resources is uncertainty in power generation. These uncertainties can be managed by using load response programs and energy storage systems. Another problem of the network in the use of distributed renewable resources is the islanding of a part of it, which reduces the reliability of the network. To increase the reliability of the network in these conditions, storage devices and resources are used that are placed inside the island. In this article, the reliability of the network will be investigated by finding the optimal production values of renewable resources as well as the amount of charging/discharging of storage devices, taking into account the load response in the standard 69-bus IEEE network.
