Development of Optimal Operating Model for Electrical Energy Distribution Systems with DG Units
, M.Sc. Thesis Sharif University of Technology ; Saboohi, Yadollah (Supervisor)
Abstract
The objective of the present research work has been the development of a model of optimal distribution electrical energy which may include distributed generators. Electrical distribution company has the option of receiving electric power from distributed generators owned by customers (Private Companies), DGs belonging to the electrical distribution company and purchase of power from market (high voltage network). The electrical distribution company would alternatively be able to sell surplus of its generation to the power market (high voltage network). The model of distribution system depicts the flow of electricity in each hour interval. The restrictions and bounds are the flows in each...
Short-term Scheduling of Generation Units Considering Effective Uncertainties and Their Economic Effects

Abstract
The objective of the short-term scheduling of generation units has been changed with the restructuring of power systems. Minimizing the total operation cost while satisfying system operation constraints is the main objective of short-term scheduling of generation units in an integrated or centralized power system. Unlike the vertically integrated power systems, the main objective of Generation Company (GenCO) is maximizing the total profit in the restructured system. Two new approaches, called time varying acceleration coefficients iteration particle swarm optimization (TVAC-IPSO) and Imperialist Competitive Algorithm (ICA) are proposed to solve power systems static and dynamic economic...
A profit-centric strategy for distributed generation planning considering time varying voltage dependent load demand
, Article International Journal of Electrical Power and Energy Systems ; Volume 44, Issue 1 , January , 2013 , Pages 168-178 ; 01420615 (ISSN) ; Ehsan, M ; Nouri, H ; Sharif University of Technology

Abstract
This paper proposes a new algorithm to determine the best connection of multiple distributed generations (DGs) on distribution networks according to type of customers. The considered DG technology is combined heat and power (CHP) in various sizes which can be extended to other technologies. Different types of demand, such as industrial, residential and commercial are defined by the load model that is voltage dependent and the load patterns from real life hourly demand data. This method which is based on multi-year multi-period power flow is useful for Distribution Network Operators (DNOs) when they are faced with voltage dependent load models in their networks. However it can be used in...
