A novel combined evolutionary algorithm for optimal planning of distributed generators in radial distribution systems
In this paper, a novel, combined evolutionary algorithm for solving the optimal planning of distributed generators (OPDG) problem in radial distribution systems (RDSs) is proposed. This algorithm is developed by uniquely ...
Multiobjective optimal power flow using a semidefinite programming-based model
In spite of the significant advance achieved in the development of optimal power flow (OPF) programs, most of the solution methods reported in the literature have considerable difficulties in dealing with different-nature ...
Impact of distributed generation on protection and voltage regulation of distribution systems : a review
During recent decades with the power system restructuring process, centralized energy sources are being replaced with decentralized ones. This phenomenon has resulted in a novel concept in electric power systems, particularly ...
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 ...
Advanced utilization of big data for real-time monitoring and data analytics in Sundom smart grid
Modern technologies are increasingly used in many protection, control and monitoring solutions for power distribution grids. Voltage and current measurements are nowadays usually converted to digital signals, which are ...
Principles of power management in a smart microgrid based on Std. IEC 61850
In recent years, the structure of the electrical power system has changed, and all aspects of power generation have shifted towards bidirectional and smart methodology. The Microgrid (MG) as a popular concept for the modern ...
Multi-objective model for allocation of gas turbines with the aim of black-start capability enhancement in smart grids
Installation of new power generating units as backup black-start (BBS) sources is a vital issue to improve the acceleration of power network restoration, especially when a serious problem is occurred in main BS units (BSUs) ...
Prospects and costs for reactive power control in Sundom smart grid
New options to provide the technical ancillary services locally and system-wide by distributed energy resources (DER) are needed in the future. Sundom Smart Grid (SSG), local smart grid pilot in Vaasa, offers a novel ...
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 ...
Probabilistic model for microgrids optimal energy management considering AC network constraints
A new probabilistic approach for microgrids (MGs) optimal energy management considering ac network constraints is proposed in this paper. The economic model of an energy storage system (ESS) is considered in the problem. ...
