A study on transient stability of distributes energy resources in prosumer

Background/Objectives: Recently, the increase in energy consumption has continued due to continuous economic growth. We, therefore, need to develop long-term of energy supply stability through the new energy sources (photovoltaic, wind, ESS) Methods/Statistical analysis: This paper studies some efforts to achieve stability through distributed generation in prosumer system through line faults and sudden load change. This paper also analysis transient stability of Distributed Energy Resources by penetration level. Findings: Distributed generations have many sources for generation, so it is classified as rotary machine and non-rotary machine by generation characteristics. Rotary machine is divided between synchronous machines(generator) and asynchronous machines(wind power system). Non-rotary machine is divided between controllable machine (Energy Storage System) and uncontrollable machine(Photovoltaic system). This paper makes a model of Distributed Energy Resources with Graphic Model Builder and simulates PSS/E Dynamic Simulation. We will analyze transient stability of Prosumer system with penetration level of Distributed Energy Resources. Improvements/Applications: This paper can effect of stability in Prosumer system with distributed generation and can be adapted operating prosumer system and isolated power system.
