The continuous spread of distributed energy resources (DERs) such as combined heating and power (CHP), diesel generators, boilers and renewable energy sources provide an effective solution to energy related problems to serve the power and heat demands with minimum cost. Moreover, the DERs may play a significant role for supplying power and heat in rural areas, where grid electricity is not avai...

one of the main features of high throughput computing systems is the availability of high power processing resources. cloud computing systems can offer these features through concepts like pay-per-use and quality of service (qos) over the internet. many applications in cloud computing are represented by workflows. quality of service is one of the most important challenges in the context of sche...

With the growth of demand for electrical energy, it is a common practice in the power industry to shorten the maintenance duration and often to postpone maintenance tasks. Maintenance or overhaul of generating units is one of the crucial factors in delivering reliable electrical energy. A large part of the overhaul work is to examine the condition of the mechanical and the electrical elements. ...

Microgrid (MG) is considered as a feasible solution to integrate the distributed energy sources. In this paper, optimal scheduling of a grid-connected MG is investigated considering different power sources as combined heat and power (CHP) units, only power and heat generating units, and battery storage systems. Two different feasible operating regions are considered for the CHP units. In additi...

The virtual power plant is one of the key technologies for integration various distributed energy resources into grid. To enable its smooth and reliable operation, network infrastructure that connects components critical communications becomes a research challenge. Current communication networks based on traditional Ethernet long-term evolution cannot provide required deterministic low latency ...

Demand response (DR) has become a key element in balancing the power grid as contribution of time-varying renewable generation increases. Chemical plants are appealing candidates for DR programs they offer large, concentrated and flexible loads. participation calls frequent production rate changes over time scales that overlap with dominant dynamics plant. Production scheduling should therefore...

In this paper, we address the integration of production planning and reactive scheduling for the optimization of a hydrogen supply network consisting of five plants, four inter-connected pipelines and 20 customers. We present multiperiod mixed integer nonlinear programming (MINLP) models for both the planning and scheduling levels. The planning model includes complex pricing functions resulting...

The paper deals with the problem of choosing the best O&M strategy for wind power plants. Current maintenance theory considers just production opportunities and minimizes the maintenance costs, but with the liberalization of the electricity market also the electricity price has become an important variable to take into account in the O&M scheduling. Another important variables that is often neg...
