This paper proposes a method for choosing the best coordinated expansion planning of generation and transmission systems considering an annual outage cost and a probabilistic power system reliability criterion (RLOLEGTS). The objective method minimizes a total cost which are not only an investment budget for constructing new generators and transmission lines but also an annual outage cost. Main...

Reactive power planning is one of the most challenging problem for efficient and source operation of an interconnected power network. It requires effective and optimum co-ordination of all the reactive power sources present in the network. Recently, Teaching Learning Based Optimization (TLBO) algorithm is evolved and finds its application in the field of engineering optimization. In the propose...

Wind and solar generators differ from conventional generators in their generation characteristics. The variable output and imperfect predictability of these generators face a stochastic approach to plan and operate the power system without fundamentally changing the operation and planning problems. This paper overviews stochastic modeling challenges in operations, generation planning, and trans...

System stability study is the important parameter of economic, reliable and secure power system planning and operation. Power system studies are important during the planning and conceptual design stages of the project as well as during the operating life of the plant periodically. This paper presents the power system stability analysis for IEEE9 bus test system. The fault is created on differe...

Recent trends in power systems are mostly undergoing research in the area of widespread failures. With the increase in power demand, operation and planning of large interconnected power system are becoming more complex, so power system will become less secure and stable. Operating environment, conventional planning and operating methods can leave power system exposed to instabilities. Voltage s...

the paper tries to present an improved mathematical model for distribution companies (discos) in order to solve distribution network expansion planning (dnep) problems in the presence of certain resources of distributed generations (dgs) entitled small scale gas engines in the medium voltage grids. with the aim of minimizing investment and operation costs, the recommended model combines a compr...

The proportion of renewable power generation in the world has been increasing recent years. However, fluctuations and uncertainties bring a considerable challenge to future unit scheduling. Therefore, flexibility systems becomes more critical as large amount is integrated into systems. use flexible generators with energy storage one most efficient methods improving system flexibility. primary p...

Accurate models for electric power load forecasting are essential to the operation and planning of a power utility company. Load forecasting helps electric utility to make important decisions on trading of power, load switching, and infrastructure development. Load forecasts are extremely important for power utilizes ISOs, financial institutions, and other stakeholder of power sector. Short ter...

Short-term load forecasting (STLF) is an essential procedure for effective and efficient realtime operations planning and control of generation within a power system. It provides the basis for unit-commitment and power system planning procedures, maintenance schedul‐ ing, system security assessment, and trading schedules. It establishes the generation, capaci‐ ty, and spinning reserve schedules...
