PAPER: Consumers’ flexibility estimation at the TSO level for balancing services

Find a copy of the paper here What is the Problem? Using consumers’ flexibility by the TSO is a way to provide extra AS required to accommodate higher level of renewable generation. This can be done by a time-varying prices submitted to flexible loads. However, effective models are needed for the TSO to generate price […]

PAPER: Improving predictability of renewable generation through optimal battery sizing

Find a copy of the paper here What is the Problem? Renewable energies such as PV and wind are unpredictable by nature to a large extent. Despite all the new forecasting methods, they still conservatively bid in the market and pay penalty to the ancillary services market based on causer pay. Why is it Interesting? […]

PAPER: Learning from a 3.275 MW utility-scale PV plant project: Update and new remarks

Find a copy of the paper here What is the Problem? Batteries are inevitable in the future power system. At the same time, different battery technologies are under development and lots of unknown exist to the research and engineering communities about their operation. In addition, the benefit and technical limits of operating batteries next to […]

PAPER: Utilizing flexibility resources in the future power system operation- Alternative approaches

Find a copy of the paper here What is the Problem? The future power system should accommodate large amount of variable renewable generation in order to achieve renewable targets. Also, using conventional generators to provide ancillary services in the system should be limited to special circumstances as a way to decrease emissions from power plants […]

PAPER: Optimal coordinated bidding of a profit-maximizing EV aggregator under uncertainty

Find a copy of the paper here What is the Problem? Application of EVs in providing services to the grid through aggregator depends on the economic benefits of different stakeholders. Therefore, developing appropriate aggregation algorithms that deal with uncertainties involved in the process becomes very important. Why is it Interesting? From power system operation point […]

PAPER: Evaluation of battery operation in ramp-rate control mode within a PV plant: A case study

Find a copy of the paper here What is the Problem? Batteries are used (and will be used) in renewable generation plants to compensate quick variations in the output of these resources, among other things. It could be very useful for researchers and engineers to know the kind of regime that battery will experience in […]

PAPER: Ancillary services 4.0: A top-to-bottom control-based approach for solving ancillary service problems in smart grids

Find a copy of the paper here What is the Problem? Existing Ancillary Services (AS) market and its alternative approaches are not suitable for the future power systems with large amount of renewable energy. They are slow, linear, and limited to a specific power system functionality. Why is it Interesting? This is an important problem […]

PAPER: An advanced retail electricity market for active distribution systems and home microgrid interoperability based on game theory

Find a copy of the paper here What is the Problem? Active distribution networks are the future of power system with prosumers. Currently, there is no market mechanism to encourage energy exchange among prosumers to increase competition with the utility companies. Why is it Interesting? The prosumers can trade energy and ancillary services among each […]

PAPER: The Impact of Temperature On Battery Degradation for Large-Scale BESS in PV Plant

Find a copy of the paper here What is the Problem? Large-scale batteries generate heat during charging and discharging events. So, we are interested to know the impact of charge/discharge regime on the generated heat. Also, it is quite important to quantify the impact of excessive heat in terms of battery degradation. Why is it […]
