Permasalahan  OPF  terdiri dari  banyaknya objective function,  an/ara  lain economic dispatch, perencanaan  VAR,   dan juga  minimisasi rugi-rugi.  Untuk perencanaan  VAR perlu  mempertimbangkan biaya operasional rugi-rugi, sehingga membentuk sua/u permasalahan perencanaan dan operasiyang simultan.Di  tulisan  ini  secara  khusus  hanya  membahas  metode  OPF  ImprovedQuadratic Interior Point (IQIP). Metode  !QIP ini memiliki unjuk kerja yang secara umum lebih  baik  dibanding me/ode   generasi   sebelumnya,   yaitu  EQJP (Extended Quadratic Interior Point),  antara lain karena bisa menggunakan titik awal general dan pada  beberapa  pengujian  lebih cepat konvergen dibandingkan EQJP. Hal ini menyebabkan me/ode IQIP mampu menawarkan perbaikan besar di dalam kecepatan,keakuratan,  dan konvergensi  di dalam pemecahan masalah optimisasi yang  multi• objective function  dan multi-constraint.   Kemampuan memecahkan optimisasi global dari sistem terinterkoneksi  dan sis/em  terpartisi  untuk optimisasi /oka/juga lebih baik dari generasi  sebelumnya.Metode ini telah melalui pengujian terhadap sis/em 14 bus, 30 bus, dan 118 busIEEE. Efektivilas dari metode  ini telah dieva/uasi dengan cara dibandingkan denganprogram OPF yang berbasis EQIP (Extended Quadratic Interior Point) dan programMINOSyang cukup dikenal di dunia perencanaan sis/em

Micro Grid

Micro-grid system is an integrated energy system as it consists of distributed energy resources (DERs) and multiple electrical loads operating in parallel or islanded grid. The primary objective of this project is to examine whether Micro-grid implementation can reduce the cost of energy. It can be determined through the modelling bus bar system; 26-Bus Test System. This application can be divided into three aspects which are modelling, simulation and analysis. The power system analysis was conducted under two conditions, steady state condition and contingencies condition using two different methods which are optimal power flow and economic dispatch. Newton-Raphson algorithm was introduced during the power flow analysis. The optimal power flow and economic dispatch for total generation cost was obtained through PowerWorld software simulation.
