Electrification is widely considered as a viable strategy for reducing the negative environmental impacts of the energy system. Following this strategy, most attention has been paid to electrification of road transportation, i.e., electric vehicles. In addition, substantial potentials could be exploited in the electrification of offshore oil and gas platforms, as an alternative to on-site gas turbines...
A Distribution System Operator (DSO) might consider a capacity contract as a planning alternative to defer grid investments. A Virtual Power Plant (VPP) might be able to provide such capacity and change its production as requested by the DSO. This article presents an assessment of the impact of this type of distribution capacity contract (DCC) on VPP's remuneration. This assessment is done by comparing...
This paper describes a new approach for optimization and simulation of hydro-thermal systems. The approach mimics how the market is operated and utilizes the same tools as the market players. One of the major complexities in hydrothermal optimization models are caused by the number of hydro storages. The proposed model solves this multidimensionality problem iteratively using price decoupling and...
The operation planning in hydrothermal systems with great hydraulic participation, as it is the case of Brazilian system, seeks to determine an operation policy to specify how hydroelectric plants should be operated, in order to use the hydroelectric resources economically and reliably. This paper presents an application of Takagi-Sugeno Fuzzy Inference Systems to obtain an operation policy (PBFIS...
This paper emphasises the importance of a well planned unit commitment model in coordination with water value evaluation to achieve optimal economic results for genco. The existing water value models are examined and customized for the developed power system model. Linear programming methods are used to achieve optimal economic performance for hydro and thermal power plants production and the power...
AI Planning typically deals with the causal relations between the actions while the role of explicit time and limited resources is suppressed. The recent trends show that integrating time and resource reasoning into planning significantly improves direct applicability of planning technology in real-life problems. In this paper we propose a suboptimal domain-independent planning system Filuta that...
In an ecologically vulnerable area, due to the severe man-land conflict and ecological vulnerability, the traditional approach of "greater agricultural placement" to the construction of investment projects would make the resources and environment of this area unsustainable, thereby affecting the effectiveness of resettlement. Therefore, it is imperative to avoid resource and environmental...
Currently in Brazil, long-term (horizon 20 to 30 years) and short-term (15 years horizon) energy expansion planning studies are carried out under the coordination of the Ministry of Mines and Energy. More recently the Federal Government has decided to carry out mid-term studies (15 years horizon). For long-term and short-term studies are adopted the computational models MELP and NEWAVE, respectively...
The genetic algorithm is a global optimization method and good at flexibility and robustness. It conducts undirected random search, which is not limited by search space. The computational procedure of the algorithm is easy and simple. The genetic algorithm is especially suited to solve multivariate and nonlinear complex problems which are impossible or difficult to be settled by other scientific technologies...
This paper presents a digital computer package for solving the complex problem of short and medium term hydro-thermal coordination and unit commitment. This package called REDPLA, is a set of advanced application programs and mathematical optimization, developed by the Electrical Research Institute in Mexico. The package is used daily by the Electric Federal Commission (EFC) in the operational planning...
