The separation of vertically integrated electric power utility in Nigeria into independent entities has opened up the requirement for information and data exchange among the new entities not only to guarantee the security and reliability of the power network, but also for accounting purposes. However, information exchange in highly heterogeneous computing environment poses a major difficulty du...

adolescents who engage in risky behavior. The third group comprises adults who work with electricity. Electrical burns account for between 3% and 7% of admissions to burn centers in the United States each year, many of which are occupational injuries. The annual occupational death rate from electrocution is 1 per 100,000; this type of death occurs more frequently in utility workers, miners, and...

We compare different multiperiod risk measures taken from the class of polyhedral risk measures with respect to the effect they show when used in the objective of a stochastic program. For this purpose, simulation results of a stochastic programming model for optimizing the electricity portfolio of a German municipal power utility are presented and analyzed. This model aims to minimize risk and...

The intermittent and unpredictable changes of power system load requires flexible generation of electricity that can rapidly adjust its output power to keep up with the fluctuations. However, many generators do not have this capability. Another option is to install utility scale energy storage. In order to evaluate the dynamics and benefits of a flywheel installation in a two-area system, a pow...

One important aspect of modern critical infrastructures (CI) like power grids is that the control of the physical processes (e.g., electricity transmission) is no longer done locally but in a distributed way with SCADA/PCS systems. This distributed control is done over utility networks, typically wide-area IP networks, that interconnect the CI facilities (e.g., transformation substations). This...

The procurement decision problem of divisible goods is investigated, and an optimization decision method for procuring a kind of divisible goods (such as coal, oil, electricity, gas, etc.) is presented based on multi-attribute auction. Firstly, the procurement decision problem of divisible goods is converted into a multi-attribute auction of divisible goods. Correspondingly, several important a...

In order to meet the energy demands from industrial processes, utility plants must convert fuel and water into steam, electricity, and rotational power. Site utility systems are operated with different scenarios or operating conditions, due to variable conditions, such as different electric power tariffs, changing load in processes and variable ambient temperature. A novel methodology for the d...
