This paper proposes a control method for allowing aggregates of thermostatically controlled loads to provide synthetic inertia and primary frequency regulation services the grid. The proposed framework is fully distributed basically consists in modification thermostat logic as function grid frequency. Three strategies are considered: first one, load aggregate provides by varying its active powe...

The increasing penetration of Distributed Energy Resources (DERs) and Generation (DG) means a paradigm change in planning operation power systems around the world. In order to understand circumvent possible challenges arising from growing energy injection at this grid level, new modeling analysis tools are required. This paper presents methodology for distribution resources system analysis. met...

The development of distributed generation based microgrids with high penetration electronically interfaced systems shows great interest in various applications. These commonly use LC-L filters inherent resonance characteristics, which increases the risk amplification and propagation microgrids. resonances lead to current voltage harmonics amplifications resulting major power quality stability i...

Energy consumption and environmental issues have become major drivers of increasing renewable energy penetration levels. The electricity generated from sources is decentralized throughout distributed generation (DG), which located at the distribution level. However, presence DG can change system characteristics affect protection systems. Thus, this study aims to investigate impact in term its s...

Wind generation connection to power system affects steady state and transient stability. Furthermore, this effect increases with the increase of wind penetration in generation capacity. In this paper, optimal location of FACTS devices is carried out to solve the steady state problems of wind penetration using Genetic Algorithm (GA). Cases studied are carried out on modified IEEE39 bus system wi...

There is scientific evidence that consumers have a growing motivation to move towards distributed generation of electricity, but the power distribution companies expressing considerable concern about impact increasing penetration rates on their revenues. In this sense, study presents analyzes and laboratory simulations based business model encourages sale surplus generation. The flow in feeders...

wind power generation is variable and uncertain. in the power systems with high penetration of wind power, determination of equivalent operating reserve is the main concern of systems operator. in this paper, a model is proposed to determine operating reserves in simultaneous market clearing of energy and reserve by stochastic programming based on scenarios generated via monte carlo simulation ...

regarding the nature of non-linear discrete placement, and in order to determine the optimal capacity of the substation, the goal in the present study will be a number of local optimum points. in this research, the problem of optimal placement posts to reduce power losses by considering distributed generation (dg). in formulating the objective function, geographical distribution density in the ...
