Recent studies have shown that multi-step optimization based on Model Predictive Control (MPC) can effectively coordinate the increasing number of distributed renewable energy and storage resources in the power system. However, the computation complexity of MPC is usually high which limits its use in practice. To improve the efficiency of MPC, in this paper, we apply a distributed optimization method...
This paper proposes an approach to formulate the multiple-period ramping capability of dispatchable generation resources and evaluates the impact of this service on the generation scheduling in day-ahead electricity market. It is discussed that the multiple-period ramping enhances the load following capability of dispatchable generation resources and improves the dispatchability of renewable energy...
With the increasing penetration of renewable resources in power systems, more operational flexibility is required to deal with the uncertainty of intermittent generation. In particular, fast acting regulation reserves are needed to maintain the load-generation balance. This paper focuses on evaluating the benefits of energy storage in providing regulation services for real-time operation. Among the...
While integrating wind power into the electricity market can reduce the operational and fuel costs of the power system, it also increases the imbalance cost and the need for reserve. Due to this contradictory, there is a need for planning the amount of wind power in the power system. This paper proposes a model to determine the real-time optimal participation of wind power in an electricity market...
Integration of a large amount of wind power to the power grid presents many challenges to the power system planners and operators. These challenges stem primarily from the natural characteristics of wind energy, which causes variable and intermittent power output, and secondarily from the missing infrastructure to bring the power from the optimal locations for wind generation to the loads. Storage...
This paper proposes a stochastic time-series based method to simulate the volatility of intermittent renewable generation and distributed storage devices along timeline. The proposed method can calculate the optimal timeline for different electricity markets and power systems. In practice, the proposed method is potentially useful for designing market rules and evaluating different design options...
This paper considers the role that energy storage may play in the evolution of wind generator technologies, and how it is managed in order to mitigate impacts related to power system operations. The management of the energy storage device is discussed along with other potential options for limiting the output power fluctuations. The concepts are demonstrated using one of the most prominent wind turbine...
