This paper presents a fast and accurate method to determine the available transfer capability. Ralston’smethod is used to predict the two trajectory points of voltagemagnitude, power flow, and maximum generator rotor angle difference. Then, the cubic spline interpolation technique is used to accurately trace the P-V, P-S, or P-Δδ curves between two points of trajectory. The P-V, P-S and PΔδ cur...

Reducing the energy consumption of heating, ventilation, and air conditioning (HVAC) systems while ensuring users’ comfort is both academic practical significance. However, the-state-of-the-art optimization model HVAC system that either thermal dynamic simplified as a linear model, or single-timescale, which leads to heavy computation burden. To balance practicality overhead computation, in thi...

We obtained the region of convergence and the summation formula for some modified generalized hypergeometric series (1.2). We also investigated rationality of the sums of the power series (1.3). As a result the series (1.4) cannot be the same rational number in all Zp. 1991 Mathematics Subject Classification: 40A30,40D99

The problem of optimal economic operation of hydrothermal electric power systems is solved using powerful continuation method. While in conventional approach, fixed generation voltages are used to avoid convergence problems, in the proposed algorithm, they are treated as variables so that better solutions can be obtained. The algorithm is tested for a typical 5-bus and 17-bus New Zealand networ...

This paper presents a novel method to calculate the reference source current and the referencecompensating current for shunt active power filters (SAPFs). This method first calculates theamplitude and phase of the fundamental load current from a recursive algebraic approach blockbefore calculating the displacement power factor. Next, the amplitude of the reference mains currentis computed with ...
