Power & Water
Systems Consultants Ltd (PWSC) was formed in 1983 to provide consultancy
services relating
to the optimal operation and development of power and
water resource systems.
Rising demands, coupled with spiralling fuel prices
and threats of greater flow variability as a result of
global warming, are heightening world-wide appreciation
of water as a valuable and limited resource. Economic,
environmental, political and regulatory pressures increasingly
require that water resource systems are operated as efficiently
and equitably as possible, and hence encourage the adoption
of advanced analytical techniques to simulate and optimise
their operation and development.
PWSC offers a range of generalised computer
software that enables users to apply proven and robust
mathematical
programming techniques within a ‘user friendly’ environment,
while providing exceptional transparency of modelling
results. Experience in analysing the operation of complex
systems throughout the world indicates the potential
for making substantial improvements in both long and
short-term operational efficiencies, whether quantified
as cost savings or improved supply reliability. Key features
of our simulation software include the ability to compare
the results of applying conventional operating rules
with more advanced system policies based on optimised
stored water values, and detailed modelling of demand
management measures.
Applications for our AQUARIUS software and related services
include:
-
Detailed
modelling and Linear Programming based simulation of
integrated water resource,
water supply
and power supply system operation;
-
Optimisation
of long and medium-term operating policies, using fully
integrated simulation
and stochastic
Dynamic Programming techniques to minimise costs while
satisfying specified supply reliability criteria;
-
Evaluation
of individual projects and optimisation of design parameters
in the context
of the recipient
system;
-
Evaluation
and optimisation of supply agreements and tariffs;
-
Determination
of maximum system yields subject to defined supply
reliability criteria.
Our
executable software is available under
perpetual or time limited licences and,
subject to agreed terms, prices can be
negotiated as a function of demonstrated
potential cost savings when applied to
specific systems.
PWSC
is active in the United Kingdom and overseas,
and has particular experience in Asia,
Africa and Latin America. It is independent
of any contracting and manufacturing interests:
