Hybrid optimization algorithm to solve the nonconvex multiarea economic dispatch problem
In this paper, multiarea economic dispatch (MAED) problems are solved by a novel straightforward process. The solved MAED problems include transmission losses, tie-line constraints, multiple fuels, valve-point effects, and ...
Security-constrained unit commitment with natural gas pipeline transient constraints
The interdependencies of power systems and natural gas networks have increased due to the additional installations of more environmental-friendly and fast-ramping natural gas power plants. The natural gas transmission ...
Multi-objective optimisation method for coordinating battery storage systems, photovoltaic inverters and tap changers
The many well-established advantages of distributed generation (DG) make their usage in active distribution networks prevalent. However, uncontrolled operation of DG units can negatively interfere with the performance of ...
Voltage control of critical and non-critical loads in distribution networks with electric spring
The electric spring (ES) is a novel voltage compensator which is series with a noncritical load to regulate the critical load voltage. The voltage fluctuation is caused by wind speed fluctuation, load fluctuation, and ...
Optimal expansion planning of active distribution system considering coordinated bidding of downward active microgrids and demand response providers
(Institution of Engineering and Technology, 2019-03-14)
This paper addresses an integrated framework for expansion planning of an Active Distribution Network (ADS) that supplies its downward Active MicroGrids (AMGs) and it participates in the upward wholesale market to sell its ...
Analysis Application of Controllable Load Appliances Management in a Smart Home
(Molecular Diversity Preservation International (MDPI), 2019-09-27)
The residential sector is one of the sectors with the highest rates of electricity consumption worldwide. For years, many studies have been presented in order to minimize energy consumption at the residential level. The ...
Robust optimization framework for dynamic distributed energy resources planning in distribution networks
This study relies on a dynamic reliability-based model for distributed energy resources (DER) planning in electric energy distribution networks (EEDN) with the aim of maximizing the profit of EEDN companies by increasing ...
Integration of emerging resources in IGDT-based robust scheduling of combined power and natural gas systems considering flexible ramping products
Wind energy sources have created new challenges in power system scheduling to follow the network load. Gas fired units with high ramping could better deal with inherent uncertainties of wind power compared to other power ...
Demand response method for smart microgrids considering high renewable energies penetration
One of the most important reasons of smart grids (SGs) is renewable energies (REs) increase and demand response (DR). Present methods are not practical in the case of high REs presence in SGs and should be revised. The ...
Co-optimization of transmission switching and variable reactance devices control under worst-case wind uncertainty
The work reported in this paper jointly addresses two major challenges in modern power systems: 1) systematically maximizing wind power generation (WPG) utilization under worst-case uncertainty and 2) employing mixed ...
