A microgrid is composed of distributed power generation systems (DGs), distributed energy storage devices (DSs), and loads. To maintain a specific frequency in the island mode as an important requirement, the control of DGs output and charge action of DGs are used in supply surplus conditions and load-shedding and discharge action of DGs are used in supply shortage conditions. Recently, multiag...

Because of the high volume and unpredictability arrival of data streams, stream processing systems may not always be able to keep up with the input — resulting in buffer overflow and uncontrolled loss of data. Load shedding, the prevalent strategy for solving this overflow problem, has todate been considered for relational stream engines. On the other hand face additional challenges and opportu...

This paper presents a mixed integer linear programming formulation for load-side control of electrical energy demand. The formulation utilizes demand prediction to determine if control actions are necessary, and it schedules both shedding and restoration times based on an optimization model that minimizes the net cost of load shedding. Operational constraints are satisfied through the use of mi...

Load shedding has been extensively studied because of multiple power system failure occurrences worldwide. Reliable techniques are required to provide rapid and precise load shedding to avert voltage collapse in power networks. Meta-heuristic optimization approaches are currently the widely developed methods because of their robustness and flexibility in dealing with complex and non-linear syst...

Energy is the basic necessity for the economic development of a country. Many functions necessary to present-day living grind to halt when the supply of energy stops. It is practically impossible to estimate the actual magnitude of the role that energy has played in building up present-day civilization. In this modern world, the dependence on electricity is so much that it has become a PART & P...

The VuSystem is a software-intensive video environment developed on operating systems without real-time features. In the course of our work with this system, interesting questions have been brought up about how resources on a workstation can be best divided between applications, and what resource management features (if any) are required. This paper’s main purpose is to outline a rationale for ...

In network monitoring, an important issue is the number of tuples the data stream management system (DSMS) can handle for different network loads. In order to gracefully handle overload situations, some DSMSs are equipped with a tuple dropping functionality, also known as load shedding. These DSMSs register and relate the number of received and dropped tuples, i.e., the relative throughput, and...

In this thesis, we are working on the optimized execution of very large number of continuous queries de ned on data streams. Our scope includes both classical query optimization issues adapted to the stream data environment as well as analysis and resolution of overload situations by intelligently discarding data based on applicationdependent quality of service (QoS) information. This paper ser...

This paper discusses the usability needs of mobile applications for basic business management for Micro and Small Scale Enterprises (MSEs) in developing countries. This is based on results from a user study carried out in Uganda on 30 MSEs. The study was carried out on MyShop, an easy to use mobile business management application for cash transactions and book keeping designed for micro-entrepr...

this paper proposes an optimal power flow (opf) algorithm by direct load control (dlc) programs to optimize the operational cost of smart grids considering various scenarios based on different constraints. the cost function includes active power production cost of available power sources and a novel flexible load curtailment cost associated with dlc programs. the load curtailment cost is based ...
