Dynamic Load Model within Distributed Generation Based on Bee Colony

Stable exploitation of power systems requires their ability to balance between output electrical loads in power plants and electrical loads in system. Hence, load characteristics have an important effect in system stability. Increasing the distributed generation resources penetration rate leads to create new problems in exploitation of transition and distribution systems due to using of renewable energies. Mainly, traditional power systems inject electrical energy to distributed networks through line transitions. In today’s power networks, conditions changed due to the set of distributed generation such as photovoltaic systems in distributed networks. Therefore, the system response is different from previous condition in the causing tolerance of today systems. So in this article, record a method for determining the unknown parameters of the model using stable file information that create network disturbances and model response to them, and computed in numerical protection relay with the use of honeybee optimization colony. For this purpose, the unknown load parameters are applied to bee colony by voltage character and current. Finally, the network will analyze and evaluate under consideration of short circuit.
