Under the dynamic pricing scheme, the uncleared issue is the emergent behavior of retail customers given the fact that customers have to forecast real-time price to make optimal consumption decisions. The interaction of intelligent retail customers who learn to select forecast methods drives the system dynamics. Simulation results are used to compare with analytical model to draw conclusions on the effect of different factors on the system stability.

Under this SMD implementation, the day-ahead market is a financial forward market, which does not enforce obligation on the physical generating resources to provide energy, while the real-time market involves the dispatch of physical resources to serve the real-time load in a secure and reliable manner. In this paper an over view of the real-time energy market in ISO New England is presented. Also, some operations and design challenges of the energy market was discussed.

Stochastic unit commitment (SUC) problem with wind generation uncertainty is difficult, since wind generation is intermittent and uncertain. In the stochastic programming approach, a large number of scenarios are required to represent the stochastic wind generation, resulting in large computational effort. A Markovian approach was used to formulate the SUC problem by assuming the state of intermittent generation at a time instant summarized the information of the past in a probabilistic sense, in order to reduce computational complexity.

The intermittent nature of wind generation makes it challenging, and transmission capacity constraints add a major level of complexity since with congestion, wind generation at one node may not be the same as wind generation at another node. When multiple wind farms are located at different nodes in the transmission network, the complexity increases drastically. In this paper, wind generation is formulated at the node level using discrete Markov processes, and is integrated into the nodal demand. The Markov property reduces the number of realizations of wind uncertainty over time, compared with the stochastic programming based on scenarios. To overcome the complexity because of multiple states of multiple wind farms, power flows are formulated using voltage phase angles, assuming that the power flows are dominated by the states of the two nodes connecting the line. Then the resulting flow imbalance at each node is handled by setting aside generation and transmission capacities. Numerical results of two examples demonstrate the efficiency and scalability of the new method.

The problem is formulated as an optimization problem whose objective is to find the largest operating ranges of variable resources such that the system remains feasible under any generation realizations within the range. Computing the DNE limits can be conceptually translated into finding the largest uncertain set of a robust optimization problem. Depending on the assumptions on how the system responds to the uncertainty of renewable resources, three alternative approaches are developed to convert the nonstandard robust optimization problem into linear programming, bilinear programming and two-stage robust optimization problems, respectively. Although the linear programming problem is easier to solve as compared to the other two alternatives, its resulting DNE limits are the most conservative. Therefore, the trade-off needs to be considered when deciding which approach is the most appropriate in real-time operation. A 5-bus system and the ISO New England power system are used to test the proposed approaches.
