“…The values of P f , U f and K f can be determined from equations (9) - (11) and are useful for computer applications [9,10]: where 'elev' is the elevation of the conductor above mean sea level (ft) and t f is the air film temperature.…”

Voltage problem is always a critical issue in operating a distribution system. The uncertainties of load distribution and variation have introduced a great complexity to the task of maintaining system voltage within the permitted range. In this paper, small-scale generator, known as distributed generation (DG), is employed in the system and acting as a voltage regulator. The output of DG is controlled in such a way that acceptable level of electrical supply quality is achieved with a reasonable operating cost. The DG controller is tested with a non-uniformly varying load on the time domain basis. Simulations have been conducted with both short term (few hundred seconds) and long term (weekly) load data to validate the proposed control technique. Results have proved that the system is well functioning not only technically but also economically.

“…Based on these higher allowable temperatures, one can calculate the higher Short and Long Time Emergency Ratings (STE, LTE) using the same method as provided by die IEEE standard [25]. A similar method can be found in [39].…”

“…An elevation of the conductor temperature may bring about both mechanical and electrical effects. Three primary factors must be considered when defining the thermal limit of a power line [39]: sag, loss of strength, and limitations of the conductor fittmgs. We assume that properly designed, selected, and installed fittings are not limiting factors for the thermal limit [39].…”

“…Equation 39 gives the expected value of utility in terms of the moments of the distribution and the derivatives of the utility fimction. For example, if the outcomes of an action are distributed normally, only the first two terms are significant, since the Normal distribution has only two moments, i.e., mean and variance.…”
