Analysis of Impacts on the Frequency of Electrical Systems Caused by Distributed Energy Resources
The operation of an electric grid has become an increasing challenge due to the inclusion of Distributed Energy Resources (DERs). Thus, for development of work, the IEEE 34 Bus distribution system (modified) was modeled in the PSCAD/EMTDC software. In addition to the electrical grid, a Conventional Power Plant (CPP) was built based on the operation of a Synchronous Generator (SG), to show real dynamics in frequency analysis. A photovoltaic generation system (PV) was built to be connected to the grid under study, showing that factors such as the intermittency of solar irradiation can have a negative impact on the system, and finally, built was a Battery Energy Storage System (BESS). In this way, as contribution of the work, the behavior of the frequency of an electrical system will be analyzed when the BESS is inserted commanded by a comparison block that seeks to improve the frequency of the system in the face of disturbances imposed on it, how PV system. In addition, frequency dynamics will be compared with and without BESS.
