Multistage multiobjective electricity generation expansion planning for Tamil Nadu considering least cost and minimal GHG emission

Abstract

Summary Developing countries like India necessitates installation of new power plants to meet the elevating electricity demand. Several single‐objective mathematical formulations are modeled and solved previously for short‐term and long‐term power generation expansion planning aiding power system planners to ensure optimal decision. The input data, such as forecasted demands, economic and technical data of the generating units are numerous and unmanageable to be analyzed manually. Modern power systems have faced major challenge in solving multiple objectives such as least cost and minimal greenhouse gas emissions simultaneously. This paper presents an application of multiobjective differential evolution algorithm to multistage, multiobjective generation expansion planning problem for Tamil Nadu, a state in India. The multiobjective generation expansion planning problem has been solved for short‐term (6 years) and long‐term (12 years) planning horizon by considering 8 different cases and also compared with Nondominated Sorting Genetic Algorithm version II.

Least‐cost generation expansion planning using whale optimization algorithm incorporating emission reduction and renewable energy sources

“…The solar power plants with storage facilities are added with base plants as an alternate, and the resulting system is used to obtain the optimal (best) plan over 14 years (seven stages). The solution is obtained after 10 runs with three different cases for each run according to population size 15, 20, 25, and. Table shows the solution matrices of all the scenarios undertaken in this study.…”

“…A comprehensive review of optimization techniques and comparison among each other is also provided while focusing on the uncertainty and variability of RES . Bhuvanesh et al solved a multi‐objective multistage GEP problem by DE algorithm while taking into account the least green house gas (GHG) emissions . Rajesh et al combined wind power units, solar power units, and solar power with storage facility with the conventional GEP problem and solved using DE algorithm.…”

“…In this work, FOR value of the solar PV system is considered as 70%. 44 A total of 147.2 MW is allocated as reserve margin for conventional New England 39 bus system and 187.28 MW is allocated as reserve margin for a solar integrated PV system. This generation reserve is allocated to all the generators uniformly.…”

Research on Home Energy Management Method for Demand Response Based on Chance-Constrained Programming

“…Traditional household appliances are gradually transformed into intelligent appliances that can realize automatic and smart control, and uncontrollable household load are turned into productive and flexible demand response (DR) resources. Great potential for supporting and assisting the operation of power systems [1]. Therefore, together with the traditional power generation, households play an increasingly important role to improve the stability and economic operation of the power system.…”
