In this paper, a novel algorithm for the load flow analysis problem in an islanded microgrid is proposed. The problem is modeled without any slack bus by considering the steady state frequency as one of the load flow variables. To model different control modes of DGs, such as droop, PV and PQ, in an islanded microgrid, a new formula for load flow equations is proposed. A hybrid optimization alg...

Due to the increasing interest on renewable sources in recent years, the studies on integration of distributed generation to the power grid have rapidly increased. In order to minimize line losses of power systems, it is crucially important to define the size and location of local generation to be placed. Minimizing the losses in the system would bring two types of saving, in real life, one is ...

In a multi-regional interconnected grid, the probabilistic load flow (PLF) of any region cannot be calculated individually but should consider uncertainties introduced in other areas. Accordingly, topologies, loads, and generations every are needed. Although renewable generation data could assumed as publicly known, some regional independent system operators (ISOs) still would not share importa...

Solar PV and wind energy are the most important renewable sources after hydroelectric with regard to installed capacity, research spending attaining grid parity. These sources, including battery storage systems, well-established load modeling have been pivotal success of planning operation electric microgrids. One major challenges in renewable-based DGs, storage, loads microgrids is uncertainty...

voltage control is one of the imperative issues in the smart distribution control system. while traditional distribution network is equipped with communication and monitoring equipment, the online voltage control can be perfectly achieved. with using these smart grid technologies, the distribution voltage control schemes should carry out intelligently and cover the undesirable effect of high pe...

This paper presents a method for the optimal allocation of Distributed generation in distribution systems. In this paper, our aim would be optimal distributed generation allocation for voltage profile improvement and loss reduction in distribution network. Genetic Algorithm (GA) was used as the solving tool, which referring two determined aim; the problem is defined and objective function is in...
