Energy balance in Kuopio
|Moderator:Jouni (see all)|
|This page is a stub. You may improve it into a full page.|
The page gives information on the energy balance in Kuopio, taking into account energy input from a all sources and how these energy are used by society (domestic, industrial et.c) There is an adequate breakdown of information on energy production, distribution and consumption, however some of the information e.g the data page are not very easy to interpret.
What are the amounts of energy produced, consumed, imported, and exported in Kuopio?
### This code was run from page [[Energy balance in Kuopio#Answer]] library(OpasnetUtils) library(ggplot2) N <- 10 objects.latest("Op_en5141", code_name = "initiate") balance <- Ovariable("balance", ddata = "Op_en5469.equations") balance@data$Policy[balance@data$Policy == ""] <- NA # Prepare indices for fillna. This should be part of fillna. balance@data$CHPcapacity[balance@data$CHPcapacity == ""] <- NA balance@data <- fillna(balance@data, marginals = 1:2) # Fill empty slots in indices. nonlinearity <- Ovariable("nonlinearity", ddata = "Op_en5469", subset = "Nonlinearity parameters") directinput <- Ovariable("directinput", ddata = "Op_en5141", subset = "No modelled upstream variables") energy.balance <- EvalOutput(energy.balance) oprint(summary(energy.balance)) ggplot(energy.balance@output, aes_string(x = "energybalanceVars", y = "energy.balanceResult", fill = "Policy")) + geom_boxplot() + theme_grey(base_size = 24) + theme(axis.text.x = element_text(angle = 90, hjust = 1))
Numbers are based on op_fi:Energiatase/Kuopio.
There are several energy transformations that each describe a specific process of energy production or use. Per unit activity, there is a constant amount of different inputs and outputs into and from this process, respectively. These unit processes are used for Kuopio in such a way that one critical input or output from each relevant energy transformation is listed here; all other inputs and outputs logically follow from the nature of the transformation process.
|1||Biofuel||CHP renewable = CHP peat||1||Biofuel policy contains half biofuels, half peat|
|2||BAU||CHP renewable = 89.24||1|
|3||CHP peat + CHP renewable + CHP oil = CHP heat + CHP electricity + CHP loss||1|
|4||CHP peat = 90-98*CHP oil||1|
|5||CHP<1000||CHP electricity + CHP loss = 0.689*CHP heat||1|
|6||CHP<1000||CHP heat + CHP loss = 2.852*CHP electricity||1|
|7||CHP>1000||CHP loss = 0.2542*CHP heat||1|
|8||CHP>1000||CHP heat + CHP electricity + CHP loss = 1000||1||Maximum production of 1000 added to the CHP plant to see non-linearities|
|9||H biogas + H oil = H heat + H loss||1|
|10||H oil = 18.973*H biogas||1|
|11||H heat = 14.082*H loss||1|
|12||Ind peat + Ind oil + Ind renewable = Ind electricity + Ind process heat + Ind loss||1|
|13||Ind oil + Ind renewable = 2.014*Ind peat||1|
|14||Ind peat + Ind renewable = 10.083*Ind oil||1|
|15||Ind process heat + Ind loss = 6.376*Ind electricity||1|
|16||Ind electricity + Ind loss = 0.332*Ind process heat||1|
|17||CHP<1000||H heat = 0.08*CHP heat||1||Small heat plants reflect the total heat need|
|18||CHP>1000||CHP electricity = 0.4407*CHP heat||1||But if CHP capacity is overwhelmed, H heat and CHP heat are decoupled and another relation is described|
|19||Loss electricity = 0.0858*CHP electricity + 0.0858*Ind electricity||1|
|20||Loss heat = 0.0855*CHP heat + 0.0855*Ind process heat||1|
|21||Bought electricity + CHP electricity + Ind electricity = Loss electricity + Cons Home electricity + Cons Ind electricity + Cons Commerce electricity + Cons Municip electricity||1|
|22||CHP heat + H heat = Loss heat + Cons Home heat + Cons Ind heat + Cons Commerce heat + Cons Municip heat||1|
|23||Ind process heat = 400-685.4||1|
|24||Cons Home electricity = 296-400||1|
|25||Cons Ind electricity = 204||1|
|26||Cons Commerce electricity = 334-350||1|
|27||Cons Municip electricity = 50.3||1|
|28||Cons Home heat = 250-303||1|
|29||Cons Ind heat = 57.1||1|
|30||Cons Commerce heat = 224||1|
|31||Cons Municip heat = 386||1|
