The increased penetration of uncertain and variable renewable energy presents various resource and operational electric grid challenges 1 . Micro-level (household and small commercial) demand-side grid flexibility could be a cost-effective strategy to integrate high penetrations of wind and solar energy, but literature and field deployments exploring the necessary information and communication technologies...
The objective of this paper is to develop a Multi Agent System (MAS) for Outage Management in electrical energy management of a micro-grid. We consider a grid associated micro-grid which contains two systems each contains solar Photo Voltaic (PV) system, wind system, a local consumer, and a battery. First we calculate the load trends and solar and wind power produced in the two solar units. Then we...
Generation side of the Power industry has taken a major leap towards successfully extracting energy from the different Renewable Energy Sources (RES). Day-by-day continuous efforts are made in order to utilize more energy from these RES rather than depending on the conventional energy sources mainly for these reasons: to attain pollution-free environment, to minimize the fast depletion of the natural...
In this paper, we introduce a generic architecture for demand side management (DSM) and use combined model of time of use tariff and inclined block rates. The problem formulation is carried via multiple knapsack and its solution is obtained via ant colony optimization (ACO). Simulation results show that the designed model for energy management achieves our objectives, it is proven as a cost-effective...
The transition of power grids towards distributed and renewable energy generation leads to challenges with respect to stability and operation of distribution grids that have to be tackled with adequate systems, technologies, and control methods. Therefore, we propose a hierarchical control architecture for distribution grids based on the principles of Organic Computing. This paper evaluates the results...
The prevalence of the Smart Grid and its capabilities, has enabled sophisticated energy management that can be realized as a multi-constraint optimization problem and tailored to the specific scenario needs. In conjunction with the increasing introduction of Electric Vehicles (EVs), energy management tools can now consider expanded conditions including grid balance, cost optimization, EV characteristics,...
Microgrid is a key enabling solution to future smart grids by integrating distributed renewable generators and storage systems to efficiently serve the local demand. However, due to the random and intermittent characteristics of renewable energy, new challenges arise for the reliable operation of microgrids. To address this issue, we study in this paper the real-time energy management for a single...
In this paper we develop a mathematical model of the power usage of a community of 7 typical New Zealand houses with realistic demand profiles. Using mixed-integer programming (MIP) we apply load shifting and energy management techniques to minimise the overall cost of power. The loads are controlled based on their energy and state of charge, and a meaningful representation of energy has been ascribed...
As distributed power sources become increasingly prevalent in the near future, power electronics will be able to provide significant advantages in processing power from renewable energy sources using fast response and autonomous control. Fuel cells, photovoltaic devices and storage batteries sources produce a significant power in hybrid power structure. In this paper, the Uninterruptible power source...
Under integration of renewable energy resources many still understand only proof procedures to connect new power plant to public grid. The existing management systems aim to observe electrical and thermal grid condition. In defined situations renewable power plants will be turned off. Another huge problem is the natural fluctuation of direct renewable energy converter such as photovoltaic and wind...
