An Improved Under-Frequency Load Shedding Scheme in Distribution Networks with Distributed Generation
When a distribution network consisting of Distributed Generations (DGs) is disconnected from upstream network, the system may be exposed to severe power imbalance. In order to prevent the damage of power plants, frequency relays operate and remove DGs from the network. In contrast to traditional methods, the main objective in new methods is to keep DG units in service in the islanded distributi...

متن کاملUnder Frequency Load shedding Algorithm in Smart Islanded Networks Using Loads Frequency Index
This paper presents an optimal method of frequency load shedding (UFLS) based on the rate of change of frequency of load (ROCOFL) in islanded distribution networks (DN). The proposed method minimizes the average amount of penalties paid by the independent operator of the network by utilizing the relevant cost function. The function of islanded distribution network occurs after an error in the s...
متن کاملSwarm Evolutionary Programming for Under-Frequency Load Shedding
In this paper, Swarm Evolutionary Programming (SEP) method incorporating modified System Frequency Response (SFR) model is proposed to solve the optimal Under-frequency Load Shedding (UFLS) scheme design problem. The objective function of this problem is to minimize transient frequency and steady-state frequency deviation from nominal and total quantum of load shedding. The constrained optimiza...
متن کاملCoordinated Scheme of Under-Frequency Load Shedding with Intelligent Appliances in a Cyber Physical Power System
The construction of a cyber physical system in a power grid provides more potential control strategies for the power grid. With the rapid employment of intelligent terminal equipment (e.g., smart meters and intelligent appliances) in the environment of a smart grid, abundant dynamic response information could be introduced to support a secure and stable power system. Combining demand response t...
