Optimal real power dispatch of centralized micro-grid control operation

A Microgrid (MG) low voltage network basically consists of Distributed Energy Resources (DERs), storage devices and controllable loads which can operate in grid tied or islanded mode. Optimal power flow (OPF) is carried out for minimum operational cost based optimal scheduling in day ahead pricing market with forecasted data of DERs generation and daily hourly residential load profile. Optimal scheduling helps to maximize overall profit of Micro grid controller (MGCC) in centralized control mode operation of micro-grid where owners have common goal of profit maximization achieved with cooperation in order to meet their individual goal. Linear programming method of optimal power flow is used for the cost minimization purpose and Newton's method for power flow to estimate initial cost of dispatch.
