Distributed Interruptible Load Shedding and Micro-Generator Dispatching to Benefit System Operations

Distributed Load-Shedding System for Agent-Based Autonomous Microgrid Operations

A microgrid is an eco-friendly power system because renewable sources are used as main power sources. In the islanded operation mode of a microgrid, maintaining the balance between power supply and power demand is a very important problem. In the case of surplus supply, decreased generation output and/or charge of distributed storages can be applied to solve the imbalance between power supply a...

Smart load shedding and distributed generation resources rescheduling to improve distribution system restoration performance

After a permanent fault occurs if it is not possible to supply the load in the network, the optimal load restoration scheme allows the system to restoration the load with the lowest exit cost, the lowest load interruption, and in the shortest possible time. This article introduces a new design called Smart Load Shedding, abbreviated SLS. In the proposed SLS scheme, the types of devices in smart...

A benefit comparison of Load Shedding versus use of Distributed Generation

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...

Risk Analysis of Interruptible Load Contracts∗

Deregulation of electricity industries often poses enormous risk for retailers who must purchase electricity from spot markets at volatile prices and sell it to end-use consumers at stable retail rates. Absent any demand-side response, one recourse available to retailers in order to hedge against this exposure is to offer interruptible load (IL) contracts. These financial instruments enable the...
