The gradual active load penetration in low-voltage distribution grids is expected to challenge their network capacity in the near future. Distribution system operators should for this reason resort to either costly grid reinforcements, use of low-voltage boosters, or demand response (DR) mechanisms. Since DR implementation is usually more cost effective, it is the favorable solution to avoid or delay...
In this paper, application of demand response to accommodate maximum PV power in a low-voltage distribution network is discussed. A centralized control based on model predictive control method is proposed for the computation of optimal demand response on an hourly basis. The proposed method uses PV generation and load forecasts, network topology and market price signals as inputs, limits of network...
This paper presents a novel power loss minimization approach in distribution grids considering network reconfiguration, distributed generation and storage installation. Identification of optimum configuration in such scenario is one of the main challenges faced by distribution system operators in highly active distribution grids. This issue is tackled by formulating a hybrid loss optimization problem...
The electrification of heating and transportation along with the penetration of renewable energy in electricity networks has necessitated the evolution of low voltage distribution grids into smart grids. Contemporary, smart grids are realised by smart meter installations to electricity end users. In the literature, these meters aim at online metering of the grid status. Depending on this status, proactive...
Recent technological developments have facilitated the emergence of smart grids. In the smart grid perspective, metering and communication functionalities of the grid are greatly enhanced, thus boosting its observability and load management capabilities. This is an ideal scenario which is frequently encountered in contemporary literature. Unfortunately, in reality, operational and financial reasons...
In the Smart Grid context, one of the most broadly investigated areas is the matter of flexibility. This term is still not defined in a unified way. As such, it is frequently encountered in both transmission and distribution system studies, nonetheless, with various perspectives. To some extent, the reason for this is that flexibility is a multidimensional commodity. It can be associated with a unit...
This paper proposes an optimization algorithm to find the maximum wind installation in a radial distribution network. The algorithm imposes a limit on the amount of wind energy that can be curtailed annually. The algorithm implements the wind turbine reactive power control and wind energy curtailment using sensitivity factors. The optimization is integrated with Monte Carlo simulation to account for...
