“…The electrical industry over the years has been dominated by an overall authority known as vertical integrated utility having authority over generation, transmission and distribution of power within its domain of operation [1]- [2], [7], [8]. With the emerging or various independent power producers in the power market motivates the necessity of deregulation of the power system were the power can be sold at a competitive price performing all functions involved in generation, transmission, distribution and retail sales.…”

In a deregulated power system regulating the ancillary services is one of the most important issues. The present work focuses on regulating load frequency control ancillary service in a deregulated scenario with integration of potentially developing combined cycle gas fired power plants. A conventional Proportional Integral and derivative controller is used as a supplementary controller to optimize the regulation using Meta heuristic firefly algorithm. Using ITAE as performance criteria to be optimize, the PID controller parameters: proportional (K p ), Integral (K i ), and Derivative (K d ) gains are optimized using the proposed Algorithm by considering the possible feasible bilateral contracts between the various DISCOs and GENCOs of the deregulated power system. The proposed control strategy is investigated on a two-area interconnected power system consisting of Hydro-Thermal unit in the area-I and Thermal-Gas unit in area-II. The main objective of optimization is to improve the dynamics of LFC such as improving of the transient response of frequency and tie-line power oscillations and to optimizing the Power generated by various GENCOs according to the scheduled bilateral contracts. The simulation results show the PID controller tuned by Firefly algorithm (FA) exhibits a considerable improvement in dynamic performance of LFC.

“…The AGC model from [1]- [4] is modified to include delays. In an open communication system, delays can arise during: 1) transmission of ACE signals from the control center to the individual units and 2) from a telemetry delay when the RTUs send the telemetered signals to the control center.…”

“…The regulation is to increase or decrease the generation, and eventually, the mismatch, should return to zero. The ACE is formulated by the following equation [4]: (1) This equation for the ACE has three components. The first component accounts for deviations in the net tie-line flow interchange with all neighboring areas.…”

Load frequency control has been used for decades in power systems. Traditionally, this has been a centralized control by area with communication over a dedicated and closed network. New regulatory guidelines allow for competitive markets to supply this load frequency control. In order to allow an effective market operation, an open communication infrastructure is needed to support an increasing complex system of controls. While such a system has great advantage in terms of cost and reliability, the possibility of communication signal delays and other problems must be carefully analyzed. This paper presents a load frequency control method based on linear matrix inequalities. The primary aim is to find a robust controller that can ensure good performance despite indeterminate delays and other problems in the communication network.

“…There are many papers researching on load following service [1]- [5]: For large-scale power consuming corporation, [1] gives the definition of gateway energy balance between the corporation and regional power grid and builds a balance model for power generation and consumption. In [2], the attention is focused on the load following and the paper proposes a competitive way to provide this service through bilateral contracts between supplier and customer; In [3] a new method is developed for correlating system imbalances with unbalanced transactions in a bilateral transaction-based market; Reference [4] continues to investigate a possible method to realize the load-following feature of wind turbine generator; Reference [5] builds a This work was supported by National Natural Science Foundation of China (61174146, 61221063, 61304212, U1301254) reactor core model and studies an optimal time control method for load following operation of nuclear reactors.…”

In enterprise microgrid such as steel plants, the selfgenerating output is not equal to the electricity load because of the electricity load uncertainty and the self-generation power plant's limits. In order to decrease the unbalance punishment cost caused by the non-equality, electricity self-balancing multilevels model in which load uncertainty is described by a certain interval and the objective is to minimize the unbalance punishment cost and load shifting cost at the worst case is built based on the robust optimization in this paper. The multi-levels model is equivalently transformed to single level model using a set of constraints instead of the lower problem to improve the efficiency of solution. Finally, the paper tests an enterprise microgrid and the results show that proposed approach can decrease the total cost and the unbalance obviously.
