Load restoration methodology considering renewable energies and combined heat and power systems

Abstract

Outages and faults cause problems in interconnected power system with huge economic consequences in modern societies. In the power system blackouts, black start resources such as micro combined heat and power (CHP) systems and renewable energies, due to their selfstart ability, are one of the solutions to restore power system as quickly as possible. In this paper, we propose a model for power system restoration considering CHP systems and renewable energy sources as being available in blackout states. We define a control variable representing a level of balance between the distance and importance of loads according to the importance and urgency of the affected customer. Dynamic power flow is considered in order to find feasible sequence and combination of loads for load restoration.

Survey of Power System Restoration Documents Issued from 2016 to 2021

“…Also, [92] manages the load restoration procedure to assure early restoration of near and important loads, using an objective function that considers the effects of load importance and the distance from a load to generators. For this purpose, at each step, the greedy algorithm is used to select the load that will be restored without violating the system frequency.…”

“…As described in [109], the field test results show that VSC-HVDC can be treated as a great black-start source in power system restoration because it can excellently control voltage and frequency, independently adjust active and reactive power, and also execute soft energization to prevent inrush current and overvoltage problems, after an equipment energization. en, the requirements for VSC-HVDC A method to control load energization during restoration [91] A greedy algorithm to determine load energization [92] Optimal black start allocation…”

“…This makes it much easier to identify the common elements of machine condition monitoring schemes. The present paper discusses the fundamentals of Motor Current Signature Analysis (MCSA) plus condition monitoring of the induction motor using MCSA [4].…”

Energy Management Optimization and Voltage Evaluation for Residential and Commercial Areas

“…The optimization algorithms used for direct load control schemes are for certain types of loads (for example, refrigerators or air conditioning [11][12][13][14][15]); these algorithms are not suitable for large loads such as commercial or industrial loads. In Reference [16], a strategy of load management was proposed.…”
