Towards leveraging discrete grid flexibility in chance-constrained power system operation planning

Chance-Constrained Day-Ahead Hourly Scheduling in Distribution System Operation

This paper aims to propose a two-step approach for day-ahead hourly scheduling in a distribution system operation, which contains two operation costs, the operation cost at substation level and feeder level. In the first step, the objective is to minimize the electric power purchase from the day-ahead market with the stochastic optimization. The historical data of dayahead hourly electric power...

Optimal Operation of Doubly-fed Induction Generator used in a Grid-Connected Wind Power System

In this paper, a wind power system based on a doubly-fed induction generator (DFIG) is modeled and simulated. To guarantee high-performance control of the powers injected into the grid by the wind turbine, five intelligent super-twisting sliding mode controllers (STSMC) are used to eliminate the active power and current ripples of the DFIG. The STSMC controller is a high-order sliding mode cont...

Towards Realistic Flow Control in Power Grid Operation

Power Grid Dynamics: Enhancing Power System Operation through Prony Analysis

Prony Analysis is a technique used to decompose a signal into a series consisting of weighted complex exponentials and promises to be an effi cient way of recognizing sensitive lines during faults in power systems such as the U.S. Power grid. Positive Sequence Load Flow (PSLF) was used to simulate the performance of a simple two-area-four-generator system and the reaction of the system during a...

Role of Smart Grid to Power System Planning and Operation in India

Indian giant power system is facing the various problems. Due to these problems, the growth of electricity market is very slow. The present grid system in this country is incapable to handle these discrepancies. To handle these discrepancies and other typical snags in power system, there is a need to complete automation. Viewing these problems Smart Grid technologies is to be introduce/embedded...
