Optimization in general, is the search for a feasible operational policy that maximizes or minimizes the value of the objective function.
Hydropower is non-linear function though the operation problems in hydropower are non-linear problems. The best solution to non-linear problems can be obtained by application of non-linear optimization techniques.
Optimal operation of hydropower systems, reservoir(s) and associated power station(s) depends on a large number of variables and constraints, which interact in an infinite number of combinations. Therefore is extremely complex to derive in advance, a universal operating rule that would allow Optimal operation in all situations.
Real-time optimization overcomes the problem by analyzing each combination of variables as it happens (in real-time) and provides an optimum operating rule for each particular situation. The derived operating rule can be applied immediately.

MAXHYDRO is an excellent tool for Real Time operation of Hydropower Systems. It provides an optimal or best-fit solution to the operational dilemmas faced by hydropower system operators.

What is MaxHydro?

MaxHydro is a set of interlinked computer programs that can be used as a decision support tool for hydropower system planning, analysis and operation. Using a mathematical model of a hydropower system, the programs provide an optimal or best-fit solution to the operational dilemmas faced by hydropower system operators. Use of the program can result in significant improvements to daily energy production or revenues. It is an optimization program because it is based on mathematical formulation of the hydropower system and provides an optimal solution to the problem depending on the selected objective function taking into account numerous constraints.

Long term reservoir operation of hydropower stations
Short term Real-Time reservoir operation any 1/4, 1/2 or 1 hourly time steps
Excellent tool for planning of energy production for new hydropower schemes
Multi purpose reservoir modeling and analysis-Including irrigation and water supply
Hydrothermal coordination

"MAXHYDRO is doing a good job for our requirements"
Ontario Power Generation - Canada 

With more than 30 years experience in software development and hydropower optimization MaxHydro is a name you can trust.

The software was developed by Dr. Zoran Petreski a Civil Engineer BSc with major in Hydraulic Engineering, and PhD and MSc degrees in Planning and Management of Complex Water Resources Systems. Successfully completed two additional postgraduate study courses in Water Resources Management (Italy 1990) and Hydroinformatics (The Netherlands 1991).

As a design engineer, Zoran provides innovative, reliable end cost-effective solutions, combined with the expertise in numerical modelling to efficiently formulate and solve complex hydraulic engineering problems. As a hydraulic or hydrological modeller Zoran can apply and use various numerical techniques to formulate and solve simple and complex water resources problems. And as a computer programmer Zoran can successfully produce engineering tools, which encapsulate the wide knowledge and experience into simple and easy to use computer programs that can boost the productivity of the design team.

Proficient in the numerical modelling and analyses, have used finite difference, finite elements, method of characteristics, linear programming, dynamic programming and several other numerical techniques. Have used or familiar with the use of numerous hydraulic engineering or water resources software solutions, such as Mike11, Mike 21, Mike SHE, Mike Basin, HEC1, HEC2, HEC5, EPANET, AutoCad, WaterCad, WaterHammer and transients analysis software etc. Have used various statistical software packages and Monte Carlo, Auto Regressive AR and Auto Regressive Moving Average modelling for synthetically generating of stream flow sequences. Familiar with the GIS systems, Expert systems and proficient in use of the major SQL database servers, like MS SQL, Informix, DB2, Interbase, and have used Oasys SCADA systems, from Telvent and familiar with the OPC connectivity to SCADA.

Customization and changes

Even though MaxHydro is very complete software we recognize that it may not cover all possible scenarios and circumstances. That is the may reason why we offer customization on all aspects of the program. If you prefer different user interface, or output results, additional input parameters and/or constraints we will be able to help. We have expertise and knowledge to do the job quickly and efficiently. Please email us and will discuss it further and let you know the time and the price to complete the project.

 MaxHydro Web Interface

We have experience programmers that can port MaxHydro to a database server, like MSSQL, ORACLE, INFORMIX, IBM DB2, MYSQL, FIREBIRD/INTERBASE

We develop web sites on IIS 7 and .NET, Apache and PHP and have developed many portals or web interfaces connected to database servers.

Remote Desktop to MaxHydro on our cloud servers

We offer remote desktops connected to MaxHydro to run MaxHydro on our cloud servers. We will set up MaxHydro on our servers and issue user id and password. You will be able to run MaxHydro remotely and we will take care of all hassle to set it up and keep it up to date.  Please email us if interested.
