“…The formulations of Δ U max and Δ U min are expressed in (1–2) [25],

normalΔ U_{\max} = U_{\max} - U_{H}

normalΔ U_{\min} = U_{L} - U_{\min}

There are two types for controlling OLTC: the conventional control and intelligent control. Examples of conventional control are line drop compensation [26], source drop compensation, and pre‐emptive tap changer [27]. The conventional control methods are not efficient for mitigating voltage rise, which is caused by DG in the distribution network [28].…”

“…In the proposed grid EMS, an automatic LDC method called the vector-LDC method [10] is adopted as a tap control scheme (Figure 3 In the proposed grid EMS, the LDC parameters of voltage regulators are determined using an input-output relationship database (Figure 4), and updated each hour. [11] The relationship between the past predicted profiles of energy demand and PV output and feasible LDC parameter candidates are stored in the database.…”

This paper presents a coordinated energy management system (EMS) based on time-of-use pricing. The proposed EMS consists of prediction, operational planning, and control stages. To minimize amounts of curtailed PV output, operational costs, and voltage violations, line-drop compensation parameters are determined based on an input-output relationship database in the grid EMS. In the home EMS, an energy equipment operational plan is developed with a stochastic optimization problem (SP) to accommodate unavoidable uncertainties. Numerical simulations based on an actual distribution system model are performed, confirming the improved performance of the proposed method compared with the conventional method.

This paper presents a method to reduce the power loss during transmitting energy with different transformer setting at distribution area. Many engineers are not conscious that the transformer tap setting may affect high power loss during transmitting process. By controlling the tap changing, the system can avoid voltage unbalanced on distribution system. This research demonstrated through numerical studies using Power System Simulation for J Fundam Appl Sci. 2017, 9(3S), 685-696 686 Keywords: electrical distribution system; independent component analysis; Phyton programming; power loss; power system simulation network.
