Quality of power is becoming a very important requirement in the new, deregulated and restructured power industry [1]. The importance is associated both with a need to have a “cleaner” power delivery due to a variety of sensitive loads and with a goal to provide a premium service to gain a competitive edge. A major part of achieving higher quality of power is the ability for assessing the quali...

With the opening of the power industry to competition, the power system structure is changing. According to these changes, power system operation, planning, and control need modifications. In the past, utilities had to produce power to satisfy their customers with objective to minimize costs and all demand/reserve were met. However, it is not necessary in a restructured system. Under new struct...

To date, a number of electricity markets have deregulated, relying on market forces to set prices. The results thus far are mixed. Therefore, policy makers must rely on ex ante analyses of the market power potential for generation owners. Recently, policy makers in the Wisconsin and Upper Michigan (WUMS) electricity market have contemplated deregulation. In this paper, we examine the ability of...

In the LFC problem, the interconnections among some areas are the input of disturbances, and therefore, it is important to suppress the disturbances by the coordination of governor systems. In contrast, tie-line power flow control by TCPS located between two areas makes it possible to stabilize the system frequency oscillations positively through interconnection, which is also expected to provi...

Many restructured electric power systems use the notion of locational marginal pricing (LMP) to optimally price network congestion. In order for market participants to hedge against volatile congestion costs, as well as to spur investments, market-makers in restructured power systems offer point-to-point financial transmission rights (FTRs), whose per-unit value is defined as the difference in ...

The robust Newton–Raphson method is suggested to solve the power flow equations. Newton power flow algorithms do not automatically minimize objective function such as real power losses. Hence, this paper presents teaching learning based optimization (TLBO) approach to minimize power lossesby the optimal allocation of reactive power sources considering placement and value in restructured power s...

An ultrathin (few nanometer) polymer spacer layer is softened by local optical heating and restructured by strong capillary forces, which increase the gap between the plasmonic metal components. This results in a continuous blue-shift of the coupled plasmon from near infrared to visible with a tuning range of >150 nm that can be tightly controlled by adjusting either irradiation time or power.

In this paper, a robust genetic algorithm (GA) based multi-stage fuzzy (MSF) controller is proposed for solution of the load frequency control (LFC) problem in a restructured power system that operates under deregulation based on the bilateral policy scheme. In this strategy, the control signal is tuned online from the knowledge base and the fuzzy inference, which request fewer sources and has ...

The technologies that make this possible are those of miniaturized electronics, digital communications, inexpensive distributed computation, and advanced control software. They enable us to get rid of most of the junk that currently encumbers automobiles – engines, power trains, dashboards, and steering wheels. They allow us to define a fundamentally new, radically restructured architecture for...

As the electrical industry restructures many of the traditional algorithms for controlling generating units, they need either modification or replacement. In the past, utilities had to produce power to satisfy their customers with the objective to minimize costs and actual demand/reserve were met. But it is not necessary in a restructured system. The main objective of restructured system is to ...
