While the majority of electricity in the Nordic and Baltic countries is traded at the day-ahead market, producers and consumers can use the intraday market to adjust their production commitments according to updated forecasts closer to the time of delivery. This reduces the need for balancing, particularly important for VRE producers, but it also means that the price formation at intraday market can...
Large shares of variable renewable energy (VRE), requires flexibility solutions are developed. Considerable flexibility potentials exist from large consumers, e.g. power-to-heat (P2H) in district heating (DH). However, the existing grid tariffs obliterate the price signals from the wholesale electricity market and diminish the business cases for these technologies by increasing the costs of their...
In order to mitigate Greenhouse Gas emissions, emission trading and renewable energy support schemes have been or are going to be implemented in some developed countries or regions. Inevitably, the implementation of these two schemes would bring some new problems to electricity market operation. Given this background, with the implementation of these two schemes, an agent-based market simulation method...
This paper focuses on analysing frequency quality of Nordic power system using measurements from phasor measurement units (PMU). The PMU data of one year long period is used which has very high time resolution (20 ms per sample) and is able to provide detailed information in evaluating frequency quality and its correlation with time. The results show that the frequency quality of the Nordic power...
Under electricity market operation, the competitiveness of wind power generation may be reduced because of the stochastic nature of the wind resource, which often results in increased regulation costs. The negative impact associated to the stochastic nature of the wind resource may be reduced by coupling the wind farm with energy storage facilities, thus constituting a virtual power plant. In this...
The purpose of this paper is to discuss some of the operational concerns as the amount of wind generation in our area increases over the next 5 years. The addition of 4500 more megawatts of wind generation in California will have an impact on both the transmission system and real-time operation of the California power grid. This paper focuses on the operational issues due to the intermittent nature...
The installed capacity of wind driven generators in New York State is projected to grow from about 200 MW to as much as 2800 MW over the next ten years. Wind power promises an inconstant and largely uncontrollable source of clean and inexpensive energy. Integration of this attractive but relatively volatile resource in an electricity market demands careful consideration of the forecasting, scheduling,...
Along with the opportunity for wind power development are certain technical and operational challenges. The paper will discuss the work done by AESO with the wind industry to understand the impacts of wind generation and the current state of market and operational considerations to accommodate large scale integration of wind power in Alberta
Mathematical optimization provides a formal framework that enables systematic and transparent decision making. Significant progress has been made in recent years in applications of formal optimization techniques for competitive market based resource commitment, scheduling, pricing and dispatch. This paper describes experiences with the application of optimization technology for electricity market...
