Abstract
It has been a general practice by distribution utilities to parallel overhead distribution lines/feeders in a common right of way and the same pole as they terminate from a common substation. This paper studies the impact of modeling parallel overhead distribution lines. The modeling of this kind of circuits in the regulated status of electric [...]

Static Voltage Stability Analysis for Electric Subtransmission System
The study of voltage stability as indicated in the Philippine Grid Code (PGC) is the center of this paper. Standards and industry practice for voltage stability problem-solving are cited and were referred when provided an example simulation. Voltage stability is a must when looking at a power system if it can handle load growth and [...]

Philippine Electric Cooperative Data
It is interesting to study the electric cooperatives’ data publicly posted in websites. The following websites provide these data:
Energy Regulatory Commission (ERC)
National Electrification Administration (NEA)
Primarily, the ERC data has the following columns:
1. Distribution line length in circuit-kilometers (ckm) – this item refers to the existing [...]

Fuzzy Optimization for Distributed Generation Allocation
Abstract— Distributed generation (DG) allocation problem is addressed utilizing fuzzy multi-objective optimization in this paper. It is shown that the methodology provides needed consideration for DG allocation and accounts for uncertainty using fuzzy set theory. Voltage drop reduction, short circuit capacity (SCC) augmentation, decrease operation cost and system losses reduction were considered as objectives for [...]
