One of the main characteristics of wind power is its intermittence and unpredictability even in short time. To cope with this drawback, demand side participation has been proposed as a good complement to wind power due to its ability to manage positive and negative imbalances over time. This paper presents a mathematical model to derive the best offering strategy for virtual power plant (VPP) that...
Large capacity of wind generation is expected to be installed across Great Britain by 2020. Wind generation is variable, therefore fast ramping generation plants will be required to balance electricity demand. Gas-fired generation plants will most likely be used to compensate for wind generation variability because of their ramping capability and large installed generation capacity. This will cause...
This paper introduces a risk-based method to optimize the planning of power systems. This works uses the formulation of Energy Hub previously presented in the literature, as an interface among energy producers, consumers and the transportation infrastructure. Risk factors such as demands, operating and maintenance cost or power cost are considered in the optimization of the system. Mitigation actions...
To effectively harness the power of wind electricity generation, significant infrastructure challenges exist. First, the individual wind turbines must be sited and constructed as part of a wind farm. Second, the wind farm must be connected to the electricity grid infrastructure and the power generated managed accordingly. Due to its stochastic nature, wind energy cannot be controlled; it must be managed...
The paper investigates the case of a microgrid participating in a pool-type market to enable purchasing part of its energy demand from the grid. The market exposure subjects the ??grid to various risks including price, demand volume, non-dispatchable distributed generation output and system reliability which require extensive risk based decision making processes for optimal operational strategies...
This paper defines the current position for micro-generation, with particular reference to the potential for micro-wind units, in the Irish electricity supply system. A network model is developed using the Distflow method of load flow analysis and is applied to consider the appropriate level of micro-generation penetration.
With increasing concern over global climate change, policy makers are promoting renewable energy sources, predominantly wind generation, as a means of fulfillment of targets of emissions reduction. This paper presents a system well-being approach to calculate the system reserve useful to achieve the expected risk of Loss-Of-Load due to unit failure and uncertain nature of production of wind power,...
Because electricity is considered an indispensable resource in every home and workplace it is vital that the 'human factor' is a main concern during the development of any DSM algorithms. Appliances must be categorized as either time dependent or independent. Time dependent appliances would include TV's and cookers where the devices must operate at a user specified time. Water and space heating/cooling...
