For over a decade, distributed generations (DGs) have sufficiently convinced the researchers that they are economic and environment-friendly solution can be integrated with centralized generations. The optimal planning of requires appropriate location sizing their corresponding control various power network types to obtain best technical, economical, commercial, regulatory objectives. Most thes...

The virtual inertia technology of DGs (Distributed Generations) can provide and damping support for the power system by imitating traditional synchronous machine. However, inherent delay problems around communication process links control will make an impact on fast effect.

An islanding operation of distributed generations (DGs) in emergencies due to a fault distribution systems can be means power supply for important loads outage areas by facilitating the self-sufficient capability DGs forming microgrids. This paper presents an optimization-based intentional scheme derive near-optimal service restoration (SR) plan. The anti-parallel is considered new constraint t...

The optimal location of renewable distributed generations (DGs) into a radial distribution system (RDS) has attracted major concerns from power researchers in the present years. main target DG integration is to improve overall performance by minimizing losses and improving voltage profile. Hence, this paper proposed hybrid approach between an analytical metaheuristic optimization technique for ...

This paper proposes a service restoration model for unbalanced distribution systems and inverter-dominated microgrids (MGs), in which frequency dynamics constraints are developed to optimize the amount of load guarantee dynamic performance system response during process. After extreme events, damaged can be sectionalized into several isolated MGs restore critical loads tripped non-black start d...

The microgrid has been defined to cope with the large penetration of distributed generations (DGs). is capable operating in grid-connected mode (GC) and islanded (IS). In microgrid, (DGs) are always connected power network via inverters. Grid Connected mode, DGs commonly acts as current controlled sources retain a high grid-current quality fast dynamic response photovoltaic wind generation syst...

This paper presents an approach for daily optimal operation of distribution networks considering Distributed Generators (DGs). Due to private ownership of DGs, a cost based compensation method is used to encourage DGs in active and reactive power generation. The objective function is summation of electrical energy generated by DGs and substation bus (main bus) in the next day. A genetic algorit...

With increasing penetrations of renewable distributed generations (DGs) and electrified vehicles (EVs), the volatility of the renewable sources and the huge load of the EVs induce tremendous challenges for the power grid. The two technologies also have considerable synergetic potential to alleviate these challenges if they are intelligently coordinated. The aim of this paper is to investigate h...

In order to improve the penetration of renewable energy resources for distribution networks, a joint planning model distributed generations (DGs) and storage is proposed an active network by using bi-level programming approach in this paper. model, upper-level aims seek optimal location capacity DGs storage, while lower-level optimizes operation devices. To solve improved binary particle swarm ...

Integration of distributed generations (DGs) in power grids is expected to play an essential role in the infrastructure and market of electrical power systems. Microgrids are small energy systems, capable of balancing captive supply and requesting resources to retain stable service within a specific boundary. Microgrids can operate in grid-connected or islanding modes. Effective islanding detec...
