Zuwa Economic Dispatch
Economic dispatch (ko da ake kira economic load dispatch ko merit order) ana ce mutanen aiki mai sarrafa wanda ke tattara na gadi kan mafi girman mafi girman girman da aka fi sani don inganta hanyar zuwa masu kyau.
Economic dispatch ya bayyana hanyoyin da suka dace da shiga aiki masu zarfata a cikin gidajen gadi, zai iya yin aiki a cikin matsayin adadin kadan da ke kusa da al'amuran aiki da gudummawa, don inganta masu shiga aiki.
Economic dispatch ta haɗa da amsa da ake amfani da shi a kan makarantun gadi, ta taimaka wajen inganta hanyar zuwa masu kyau, ba tare da adadin kadan da ke kusa da al'amuran aiki da gudummawa.
Girman da suka da adadin kadan da ke kusa da tsawon zuwa masu kyau suna iya amfani da shi a karni da ake amfani da shi don inganta hanyar zuwa masu kyau. Adadin kadan da ke kusa da tsawon zuwa masu kyau na iya haɗa da adadin kadan da ke kusa da tsawon zuwa masu kyau na gadi.
Hanyoyin da ake amfani da shi a kan economic dispatch, ta taimaka wajen inganta hanyar zuwa masu kyau. Hanyoyin da ake amfani da shi a kan economic dispatch an yi a kan ido kan mafi girman mafi girman.

A kan economic dispatch, ake amfani da adadin kadan da ke kusa da zuwa masu kyau, ba tare da adadin kadan da ke kusa da al'amuran aiki da gudummawa. Saboda haka, a kan gidajen gadi, ana iya amfani da adadin kadan da ke kusa da zuwa masu kyau, ba tare da adadin kadan da ke kusa da al'amuran aiki da gudummawa.
A kan gidajen gadi, ana iya amfani da adadin kadan da ke kusa da zuwa masu kyau, ba tare da adadin kadan da ke kusa da al'amuran aiki da gudummawa. Wadannan su ne adadin kadan da ke kusa da zuwa masu kyau.
Bayanan economic dispatch
Merit order bai ci abubuwan da ke kusa da zuwa masu kyau. Makarantun gadi da suka da adadin kadan da ke kusa da zuwa masu kyau suka iya amfani da shi a karni, ba tare da adadin kadan da ke kusa da zuwa masu kyau.
Security – Constrained Economic Dispatch (SCED)
Security-constrained economic dispatch (SCED) ana ce muhimmin hanyoyin da ake amfani da shi a kan gidajen gadi. Optimal power flow (OPF) ana ce muhimmin hanyoyin da ake amfani da shi a kan gidajen gadi.
OPF ana haɗa da amsa da ake amfani da shi a kan gidajen gadi, ta taimaka wajen inganta hanyar zuwa masu kyau. Adadin kadan da ke kusa da zuwa masu kyau na iya haɗa da amsa da ake amfani da shi a kan gidajen gadi.
Akawar da hanyoyin da ake amfani da shi a kan SCED, misali linear programming (LP), network flow programming (NFP), quadratic programming (QP), nonlinear convex network flow programming (NLCNFP), da genetic algorithm (GA).
Merit Order Effect (MOE)
Adadin kadan da ke kusa da zuwa masu kyau suna iya inganta hanyar zuwa masu kyau, saboda hakan ake amfani da renewable energy sources. Hanyoyin da ake amfani da shi a kan market price ana ake kira "merit order effect."
Merit order impact a kan energy-only market ana haɗa da amsa da ake amfani da shi a kan market price, saboda hakan ake amfani da renewable energy sources. Market price ana haɗa da amsa da ake amfani da shi a kan "merit order."
Amsa da ake amfani da shi a kan market price ana haɗa da amsa da ake amfani da shi a kan "merit order." Amsa da ake amfani da shi a kan market price ana haɗa da amsa da ake amfani da shi a kan "merit order."
Market price da clearing volume ana haɗa da amsa da ake amfani da shi a kan point where the electricity supply and demand intersect. Market price na iya haɗa da amsa da ake amfani da shi a kan all market participants who operate power generators for the grid. Da kuma, market price na iya haɗa da amsa da ake amfani da shi a kan everyone who purchases electricity at the wholesale market.
Merit order sequence ana haɗa da amsa da ake amfani da shi a kan steadily falling electricity production costs, particularly in the development of renewable energy, with conventional power plants moving further behind. With the growing feed-in of renewable energies like photovoltaic, wind energy, or biomass, the effect is extremely obvious.
During peak load periods, fluctuating wind and photovoltaic power plants with marginal costs close to zero are entering the market and pushing traditional power plants toward the end of the merit order.
The merit order effect (MOE) of renewable energies is the term used by the energy sector to characterize this phenomenon. Conventional power plants just need to supply the residual load or the remaining electrical demand that renewable energies cannot meet.
