Power system simulation Wikipedia. Electrical power system simulation involves power system modeling and network simulation in order to analyze electrical power systems using designoffline or real time data. Power system simulation softwares are a class of computer simulation programs that focus on the operation of electrical power systems. These types of computer programs are used in a wide range of planning and operational situations for Electric power generation Nuclear, Conventional, Renewable. Commercial facilities. Electrical Power System Analysis Operation Software. ETAP is a full spectrum analytical engineering software company specializing in the analysis, simulation. The Constructor makes the creation, testing, troubleshooting, teaching and printing of electrical ladder diagrams, electrical schematics and electrical drawings fast. Utility transmission. Utility distribution. Railway power systems. Industrial power systems. Applications of power system simulation include Long term generation and transmission expansion planning. Short term operational simulations. Market analysis e. These programs typically make use of mathematical optimization techniques such linear programming, quadratic programming, and mixed integer programming. Key elements of power systems that are modeled include Load flow power flow studyShort circuit or fault analysis. Protective device coordination, discrimination or selectivity. Transient or dynamic stability. Harmonic or power quality analysis. Optimal power flow. There are many power simulation software packages in commercial and non commercial forms that range from utility scale software to study tools. Load flow calculationeditThe load flow calculation1 is the most common network analysis tool for examining the undisturbed and disturbed network within the scope of operational and strategic planning. Using network topology, transmission line parameters, transformer parameters, generator location and limits, and load location and compensation, the load flow calculation can provide voltage magnitudes and angles for all nodes and loading of network components, such as cables and transformers. With this information, compliance to operating limitations such as those stipulated by voltage ranges and maximum loads, can be examined. ZoFFS_Ci8nA/maxresdefault.jpg' alt='Electrical Power Simulation Software' title='Electrical Power Simulation Software' />This is, for example, important for determining the transmission capacity of underground cables, where the influence of cable bundling on the load capability of each cable has to be taken also into account. Due to the ability to determine losses and reactive power allocation, load flow calculation also supports the planning engineer in the investigation of the most economical operation mode of the network. When changing over from single andor multi phase infeed low voltage meshed networks to isolated networks, load flow calculation is essential for operational and economical reasons. Load flow calculation is also the basis of all further network studies, such as motor start up or investigation of scheduled or unscheduled outages of equipment within the outage simulation. Especially when investigating motor start up,3 the load flow calculation results give helpful hints, for example, of whether the motor can be started in spite of the voltage drop caused by the start up current. Short circuit analysiseditShort circuit analysis analyzes the power flow after a fault occurs in a power network. The faults may be three phase short circuit, one phase grounded, two phase short circuit, two phase grounded, one phase break, two phase break or complex faults. Results of such an analysis may help determine the following Magnitude of the fault current. Circuit breaker capacity. Rise in voltage in a single line due to ground fault. Residual voltage and relay settings. Electrical Power Simulation Software' title='Electrical Power Simulation Software' />Interference due to power line. Transient stability simulationeditThe goal of transient stability simulation of power systems is to analyse the stability of a power system in a from sub second to several tens of seconds. Stability in this aspect is the ability of the system to quickly return to a stable operating condition after being exposed to a disturbance such as for example a tree falling over an overhead line resulting in the automatic disconnection of that line by its protection systems. In engineering terms, a power system is deemed stable if the substation voltage levels and the rotational speeds of motors and generators return to their normal values in a quick and continuous manner. Figure 1. Specifies the acceptable amount of time it takes grid voltages return to their intended levels, which may vary depending on the magnitude of voltage disturbance. Models typically use the following inputs Number, size and type of generators with any available mechanical, electrical, and control governor, voltage regulation, etc. Var compensators, flexible AC transmission systems, etc. The acceptable amount of time it takes grid voltages return to their intended levels is dependent on the magnitude of voltage disturbance, and the most common standard is specified by the CBEMA curve in Figure. This curve informs both electronic equipment design and grid stability data reporting. Unit commitmenteditThe problem of unit commitment involves finding the least cost dispatch of available generation resources to meet the electrical load. Generating resources can include a wide range of types Nuclear. Thermal using coal, gas, other fossil fuels, or biomassRenewables including hydro, wind, wave power, and solarThe key decision variables that are decided by the computer program are Generation level in megawattsNumber of generating units on. The latter decisions are binary 0,1, which means that the mathematical problem is not continuous. In addition, generating plants are subject to a number of complex technical constraints, including Minimum stable operating level. Maximum rate of ramping up or down. Minimum time period the unit is up andor down. These constraints have many different variants all this gives rise to a large class of mathematical optimization problems. Optimal power floweditElectricity flows through an AC network according to Kirchhoffs Laws. Transmission lines are subject to thermal limits simple megawatt limits on flow, as well as voltage and electrical stability constraints. The simulator must calculate the flows in the AC network that result from any given combination of unit commitment and generator megawatt dispatch, and ensure that AC line flows are within both the thermal limits and the voltage and stability constraints. This may include contingencies such as the loss of any one transmission or generation element a so called security constrained optimal power flow SCOPF, and if the unit commitment is optimized inside this framework we have a security constrained unit commitment SCUC. In optimal power flow OPF the generalised scalar objective to be minimised is given by fu. The SCOPF is bound by equality and inequality constraint limits.
