An ISO is responsible for responsible for keeping system security within its specified limits. Rapid demand increase on one hand and less investment on transmission system and the other hand, have resulted in more stress on existing transmission grids. Therefore, various types of stability should be monitored and controlled. The small signal stability (SSS) is a type which may be improved using power system stabilizers (PSS). In this paper, though using the non-dominated sorting genetic algorithm version II (NSGA-II), it is, initially, shown how the PSSs may affect the generation cost as well as the SSS. Moreover, the service provided by PSSs is introduced as an ancillary service. A cost allocation framework is prospect in which the PSS owners are properly paid for their services provided.

In this paper, the long-term dynamics of an electricity market due to bounded rationality in investment decision is analyzed under different market designs, including energy only market (EO), market with operating reserve pricing (OR), market with fixed capacity payment (FCP) and demand curve-based capacity market (DC). System dynamics (SD) method is used to analyze the behavior. Also, the equilibrium path is determined for comparison purposes. The results indicate that the different market designs have very different dynamics and it is possible to mitigate power market dynamics by selecting proper market design. Manuscript profile

ts cause different neural responses containing a regular firing, or a long latency before firing with or without a leading spike. In this paper, the firing behavior of DCN pyramidal cells is simulated first Transmission Expansion Planning (TEP) is an important issue of power system planning studies. In literature, different methods are investigated to achieve good solutions for TEP. This paper uses Mixed Integer Linear Programming (MILP) and Mixed Integer Nonlinear Programming (MINLP) methods to study TEP. It also presents a new NLP model in which the integer variables are omitted. Moreover, the models are properly modified so that contingency conditions are also observed. Different combinations of cost functions such as the expansion cost, the operation cost and the cost of the losses are considered and compared. To reach a global optimum solution, BARON solver is applied. The proposed algorithm is applied on Garver 6-bus and IEEE-118 bus test systems. It is shown that modeling the problem by MINLP and NLP methods, in combination with a proper solver, can result in a quick optimum solution. Manuscript profile

In this paper, the long-term dynamics of an electricity market is modeled, considering the load uncertainty. Moreover, the generation side uncertainties, including the uncertainties of the generators availabilities, the hydro generations and the wind generations are observed. The problem is analyzed by the System Dynamics (SD) method. Also, the effects of capacity payment on power market dynamics, with and without uncertainties, are modeled and analyzed. The simulation results show how the uncertainties may affect the long-term behavior of a power market. Moreover, it is shown how the effect of uncertainties on market dynamics, may be improved through capacity payment. Manuscript profile

This paper proposes a comprehensive framework for distributed energy resource (DER) expansion planning from investors’ viewpoint based on a combination of dynamic programming algorithm and game theory. In this framework, different aspects of DER planning i.e. their uncertainties, risks, pollution, etc. are included. Wind turbines, gas engines and demand response (DR) programs are considered as DERs in this study. The intermittent nature and uncertainty of wind power generation and also uncertainty of demand response programs will cause the investors to consider risk in their investment decisions. In order to overcome this problem, a modified model has been derived to study the regulatory intervention impacts on wind expansion planning and implementing DR programs. Dynamic programming method is utilized for this problem solving and in each step, the Nash equilibrium point is calculated using Cournot model. A model based on intermittent nature of wind power generation and uncertainties of DR programs is developed which can calculate the optimal investment strategies. The effectiveness of the proposed model is proved through implementing on a test system. Manuscript profile

Energy exchange among the electricity markets is a new issue in modern power systems. This issue, especially in Europe, has been identified as a market coupling. In this paper, a framework for congestion management and clearing of multiple electricity markets, in which the market participants can place their bids simultaneously in different markets across an interconnection, is proposed. In this framework, the markets dispatch the energy and the reserve, independently. A central coordinator entity, then, runs the allocation of transmission capacity among the electricity markets. Three methods for simultaneous clearing of the energy and reserve are also proposed. The possibility of implementation of the proposed methods in multiple markets is discussed. The numerical results for three-area 15-bus and IEEE RTS-96 test systems in a triple-market case are presented, to demonstrate the effectiveness of the proposed approach as compared with the other approaches.

Transient stability analysis (TSA) is one of the important issues in the power system operation. The common methods of TSA are typically based on offline simulations so that some preventive and corrective actions may be designed to be adopted in real time conditions. To reduce the risk of these actions, in this paper a new method of transient stability estimation is proposed in which both local and wide-area measurements are used. According to the proposed method, the coherent generator groups of the two-area power system are initially identified and then the system is simplified based on the single machine equivalent (SIME) method. Thereafter, the equal area (EA) criterion is used to estimate the system transient stability. The innovation of this paper is the calculation of the acceleration area of SIME system based on the acceleration areas calculated locally in generator buses. The proposed method is applied on a10-mchine 39-bus test system and its results are presented by further explanation of its technical advantages. Manuscript profile
