“…However, separated generation and transmission expansion planning exercises don't guarantee minimizing the overall cost generally. The integration of these problems has been approached using different methods, models, and objective functions (for a review on the topic, see [24]). Our approach can be complementary both to an integrated and a non-integrated analysis.…”

Having a well-adapted transmission network is key for reaching a sustainable energy system, where generators and consumers participate in an efficient market. The purpose of the present research is to estimate the impact on the final prices of the interconnection of the two largest electrical systems in Chile. To this end, an econometric model is used in which prices, among other variables, are explained by the level of marginal costs in the system (opportunity cost), the degree of concentration in the market (market power), and the variability of marginal costs projected by the agents (risk). The data corresponds to bilateral contracts between generators and major clients, from 2006 to 2014. The basic results indicate that the interconnection would benefit final customers by reducing equilibrium contract prices, as a result of the decreased variability of expected marginal costs and a lower concentration of existing generating companies. This study's main contribution is to focus on the benefits of electricity interconnection under conditions of competition and risk, instead of using the simple estimation of direct costs, as has traditionally been done.

“…However, problem (12) is a constrained optimization problem, which is generally difficult to solve due to the inequality and equality constraints (8)(9)(10)(11)(12). Thus the exact penalty function method [24] is used to transform (12) into an unconstrained optimization problem.…”

“…Conventionally, the process of inland power system planning is divided into two steps, i.e., generation expansion planning (GEP) and transmission expansion planning (TEP) [7], for the following reasons: À It is difficult to deal with GEP and TEP simultaneously due to the huge number of variables [8].`The construction of power stations and transmission lines are in the charge of different sections of the power industry [9].´Over 80% of the total expansion cost goes to GEP whereas TEP only accounts for a small fraction of the investment, which leads to relatively minor errors with the two-step planning procedure [10]. Either GEP or TEP has been widely investigated in the past research.…”

To address the planning issue of offshore oilfield power systems, an integrated generation-transmission expansion planning model is proposed. The outage cost is considered and the genetic Tabu hybrid algorithm (GTHA) is developed to find the optimal solution. With the proposed integrated model, the planning of generators and transmission lines can be worked out simultaneously, which outweighs the disadvantages of separate planning, for instance, unable to consider the influence of power grid during the planning of generation, or insufficient to plan the transmission system without enough information of generation. The integrated planning model takes into account both the outage cost and the shipping cost, which makes the model more practical for offshore oilfield power systems. The planning problem formulated based on the proposed model is a mixed integer nonlinear programming problem of very high computational complexity, which is difficult to solve by regular mathematical methods. A comprehensive optimization method based on GTHA is also developed to search the best solution efficiently. Finally, a case study on the planning of a 50-bus offshore oilfield power system is conducted, and the obtained results fully demonstrate the effectiveness of the presented model and method.

“…It is inevitable to involve renewable energy in long-term Multi-Region Generation Expansion Planning (MR-GEP) [1]. In long-term MR-GEP, the objective is to expand the existing power system to serve the forecasted load over a planning horizon of typically 10-30 years.…”

Abstract-Based on duration curve method, a framework to include wind-thermal bundled power transmission pattern in multi-region generation expansion planning model is proposed in this paper. This framework proposes modelling for receiving end region, sending end region and transmission side, handling two patterns of wind-thermal bundled power transmission, fixed ancillary thermal generators and non-fixed ancillary thermal generators.Index Terms-Wind-thermal bundled power transmission, multi-region generation expansion planning, duration curve.
