Disasters, whether natural or man-made, compromise the quality of life for all involved. In such situations, expeditious recovery activities are deemed imperative and irreplaceable restoration normalcy. However, rely heavily on critical infrastructures that supply basic needs like electricity, water, information, transportation. When disasters strike, it is likely themselves affected significantly, hampering efficient processes, thus presenting a Catch-22 conundrum. this article, we present...
The provision of energy at the local level by using renewable and resources is increasingly acknowledged as a techno-economic solution for rural electrification. This work describes an approach implementing microgrid projects institutional means specific entity that uses methods engage community in operation maintenance (O&M), which ensures long-run benefits. first step, related to macro-level barriers, addressed building complete cadastre isolated communities, while second, micro level,...

We compute an optimal day-ahead dispatch plan for distribution networks with stochastic resources and batteries, while accounting grid battery losses. formulate solve a scenario-based AC Optimal Power Flow (OPF), which is by construction non-convex. explain why the existing relaxation methods do not apply we propose novel iterative scheme, corrected DistFlow (CoDistFlow), to OPF problem in radial networks. It uses modified branch flow model angle that accounts line shunt capacitances. At...
One of the key aspects enabling bulk integration photovoltaic (PV) resources into power grid is short-term prediction maximum available (from 100 ms to 5 min), and quantification associated uncertainties.

We propose validate a comprehensive method assess overall PV uncertainties, even at operating conditions different from point, i.e., consider when curtailment are adopted on...
The conventional approach for the control of distribution networks, in presence active generation and/or controllable loads and storage, involves a combination both frequency voltage regulation at different time scales. With increased penetration stochastic resources, distributed demand response, this shows severe limitations optimal feasible operation these as well aggregation network resources upper-layer power systems. An alternative is to directly targeted grid by defining explicit...

Aggregation of electric resources is a fundamental function for the operation power grids at different time scales. In context recently proposed framework real-time control microgrids with explicit setpoints, we define and formally specify an aggregation method that explicitly accounts delays message asynchronism. The allows to abstract details using high-level concepts are device grid-independent. We demonstrate application Cigre benchmark heterogenous low-inertia resources.

Abundant distributed resources surrounding isolated towns offer an unique opportunity development of smart and cost-effective microgrids allowing: efficient use local resources, reduction operational costs fossil fuels dependency, extension system components lifetime, commitment community. paper presents a microgrid design...
We consider the problem of controlling charging electric vehicles (EVs) connected to a single station that follows an aggregated power setpoint from main controller local distribution grid. To cope with volatile resources such as load or distributed generation, this manages in real time flexibility energy grid and uses adapt its consumption.

The existing approaches to control electrical grids combine frequency and voltage controls at different time-scales. When applied in microgrids with stochastic distributed generation, grid quality of service problems may occur, such as under- or overvoltages well congestion lines transformers. COMMELEC framework proposes solve this compelling issue by performing explicit power flows two novel strategies: 1) a common abstract model is used resources advertise their state real time agent; 2)...
In model based control approaches for the dynamic operation of renewable-energy microgrid, an accurate demand forecast is crucial. However, high level uncertainties in system and non-linearities make task prediction not easy. this context, we propose use a stable Takagi & Sugeno (T&S) fuzzy to perform forecasting real-life microgrid located Huatacondo, Chile. Based on real-data from northern Chile, T&S was identified compared with adaptive neural network, showing better open-loop...
