This paper proposes an optimal energy management model for a grid-connected micro-hydrokinetic pumped hydro storage (MHK-PHS) hybrid system supplying the commercial load. The aim of the model is to minimize the energy costs through power-flow control variables and time-of-use (TOU) tariff scheme. The optimization problem will be solved through the use of the linprog solver in the MATLAB's optimization...
Integrated electricity, gas, and heat district systems could potentially offer great value towards more efficient energy usage. In order to reap these benefits however, it would be of fundamental importance to determine an appropriate approach which would enable these systems to optimise their combined operation. While valuable contributions have been made in recent literature regarding multi-energy...
The widespread installation of distributed energy resources and demand side management resources into the distribution system has the potential to lead its operational parameters outside of their allowable limits. A standard strategy would be to increase the capacity of the network, however, this is costly. A cost-effective strategy could be to improve the management of such a system by improving...
This paper outlines new approaches in the fields of grid protection and optimization of distribution grid operation. The optimization aims to reduce grid losses by setting an optimal power factor at distributed energy resources at lower voltage levels. A Nonlinear programming approach is described modeling the optimization problem and causing high requirements on the mathematical formulation. Due...
