Bevrani, Hassan (2004) Decentralized robust load-frequency control synthesis in restructured power systems. Preface This dissertation is mainly focused on technical issues associated with load-frequency control (LFC) in restructured power systems. Operating the power system in a deregulated environment is more complex than in the past, due to the considerable degree of interconnection and the p...

In this paper, the parameters of PID controller for Automatic Generation Control (AGC) is tuned according to Generic Algorithms (GAs) based performance indices in the restructured power systems. The key idea of the proposed method is to use the fitness function based on figure of demerit. The simulation results are shown to illustrate effectiveness of the proposed method to solution of AGC prob...

Quality of power is becoming a very important requirement in the new, deregulated and restructured power industry [1]. The importance is associated both with a need to have a “cleaner” power delivery due to a variety of sensitive loads and with a goal to provide a premium service to gain a competitive edge. A major part of achieving higher quality of power is the ability for assessing the quali...

With the opening of the power industry to competition, the power system structure is changing. According to these changes, power system operation, planning, and control need modifications. In the past, utilities had to produce power to satisfy their customers with objective to minimize costs and all demand/reserve were met. However, it is not necessary in a restructured system. Under new struct...

It is well known that given a network that can become constrained on voltage or real power flows, reserves must also be spatially located in order to handle all credible contingencies. However, to date, there is no credible science-based method for assigning and pricing reserves in this way. Presented in this paper is a new scheduling algorithm incorporating constraints imposed by grid security...

Renewable portfolio standards (RPSs) for electricity generation are politically popular in many U.S. states although economic analysis suggests they are not first-best policies. We present an empirical analysis of the political and economic factors that drive state governments to adopt an RPS, and the factors that lead to the inclusion of instate requirements given the adoption of an RPS. We fi...
